I'm with Renegade on this... most of it, well... is not in any way worth going Google to avoid the issues with Alexa, only to gain the same issues or worse with Google... I wish my Homepods were at the level Alexa is, because the things they do... are so much smoother than both google and Alexa.
The greatest thing about the Siri, is even if someone is talking, you can get it to respond to it's wake word (Hey Siri) over a PARTY going on. Seriously the best recognition of all of them.

Over all, dollars for doughnuts, Alexa has the most compatibility of all the AI assistants, and the costs are in line with google for the most part. There are some items that work better with google home, just as the items that are better with Echo devices. so really it's nothing more than a wash on which you prefer to work with... Amazon, or Goofgle.
I suspect the Nest equipment works better with Google Home, than it would with an Echo etc...
As do Amazon outlets and other Amazon products work well with Echoes.
I like them all but wish they came to market with all functionality in place instead of having to be a beta tester for the new features every time they roll one out.

So I have programmed everything into Google Home and used it for awhile.  Like everything else, there are pros and cons but I will say now that with Google Home, the pros far outweigh the cons for me BUT read on, I still use and need both systems!!!  I also use multiple devices in a room, one has 10 devices.  I have seen many people use only up to 2 devices per group, it gets too complicated for them to use and set up... you have to be organized and consistent with your naming conventions otherwise it will be mayhem especially in Alexa.

Pros - Google command structure are so much better than Alexa especially with several items in the same group... with a few exceptions. Also, it is not prone to near as many errors as Alexa such as turning on the wrong item or even turning on items in two different groups at the same time.  Also, the issue with mixing up OFF and ON is nonexistent in Google.  Alexa also ignores a lot of commands and have to be repeated. Once a device is paired, Google will see it.  Alexa needs to register with the 3rd party first.
Cons - Google does not use 3rd party motion sensors/switches working through hubs in Routines although it recognizes them as devices.  I still have to rely on Alexa to do that BUT Alexa is known to drop these connections every now and then.  Google does not have a lot of free stuff so I still rely on Alexa for that.  I also spent a fair bit of money wetting up the Alexa quad pseudo sound system so unless I eventually get rid of Alexa, I will keep that. Google has a very annoying feature whereas it groups all lights together in a Group and turns them all on/off together regardless if you command just one.  There is a workaround for this though by making sure the device is not in any way programmed to be a light of any kind (smart bulbs must be) and don't use the word "light" in the description.  it seems Google will eventually search out and gather that item into its "light" grouping.  Smart bulbs have to be kept out of any grouping at all to avoid this issue.  I found that Google has a few commands that it just doesn't like and have to change the command to suit and change this for all devices of the type so I am consistent. Google doesn't have a whisper mode which nice very late at night but it works erratically and Alexa ends up screaming back when you don't want it too. Typical of many Alexa special features, sometimes they work, sometimes they don't.
 

hi… for the past year or so i have had a Philips Hue motion sensor working in my kitchen.
Configured in Alexa only, The routine I had was ‘If Motion detected turn on Lights, with a 4 minute suppression.
I then had a second routine which was if no Motion detected after 5 minutes turn the lights off’
this worked perfectly for over a year until the Motion detector itself seemed to get an issue. I reset the whole thing, deleted the sensor, reset and re-added.
When recreating the rules, I noticed that I no longer get the suppression option after motion is detected.
Has this been removed from Alexa? And therefore is it possible that the removal of this was my original problem?
 
appreciate any thoughts

Like others here, I am heavily invested in the Philips Hue system (hub, bulbs, lamps, strips etc).  I went with Hue, because it was the best bet at the time and has proven reliable and flexible.  I have a Hue hub and have removed all of the Echo devices with built-in hubs because they can work at cross purposes and are a bit of a pain to manage.  But that was because I was already up to my ears in Hue.

If I were to start over, I would have far fewer colour capable bulbs and probably run a split system.  I would keep some Hue lamps and strips for colour ambiance, and use a Hue hub for maximum flexibility (colour loops and other 'decorative' lighting).  But for the remainder of the house I would, probably, stick to WiFi connected devices with basic on/off/dim capability.  Also of interest in the coming years will be Matter connected devices, which may wind up being easier to manage.

Good Luck!

The question posed will have many answers. But suffice it to say, the more you spend, the more features you get, to a point. I started with Philips Hue Bulbs and have stuck with them over the times... They are arguably the most expensive consumer level LED lighting available in the US market. There are similar operating ones that are at least half the cost and perform fine for the money. The LED bulbs available at IKEA are fairly priced and are mostly similar to the Philips in their features, howver not as "rich" in colors... but most people aren't really that particular about *that level* of color range anyway, and most use them for their white lighting anyway, most of the time. I have 4 color bulbs that are rarely used as White/Ambient lighting, the rest are used in a variety of ways. Almost all of the Hue bulbs I have are color bulbs, but I do have several White/Ambience bulbs as well. You can mix and match to suit yourself.
There are so many available options it's mind numbing, but those a re a couple of the taller price range out there. The fun is making the right decision by buying items that are labeled "Works with Alexa". If you do that, you'll be fine with that stuff, although the IKEA and HUE bulbs require a Bridge to be fully featured, even if they say "Bluetooth capable".

What's the best smart bulb to get to use w Alexa?  I want to be able to turn the bulbs on and off and dim them using Alexa.

Thank you!
