Forerunner 255 Series
Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Me too. My concern is that we will be tethered to Google once they switch us. I am looking for custom high/low HR alerts and ideally workout HR-zone alerts, during exercise and my Luxe doesn’t offer that. Garmin does but don’t want a bulky watch. Hmmm.
I bought a fitbit luxe off backmarket for less than $50 this year. It's simple, but it tracks swims.
My seventh Fitbit died last week (from Luxe to Versa to Charge 5 and 6, this was my second in-warranty replacement), white line on the screen to no screen at all within 24 hours. So with some Target credit I decided to go with a Garmin Instinct for $200. The GPS is much, much more accurate (even when not paired with my phone), the app tracks a lot more information than the Fitbit app did and takes up a third of the space on my phone. I miss the constant step updates; the Garmin just updates every minute. That's about the only drawback.
My wife also has the Luxe, mainly because she has small wrists. I've tried to talk her into replacing it with a Lily, but no luck so far. I have a Forerunner 955 and I put it on her once, it was almost comically huge :) It's good to hear someone made the transition and didn't regret it!
I have a Fitbit luxe, some nights I feel I don't sleep well and when I look at my score in the morning it's in the 80's so I don't know what it goes off of I know my deep sleep sucks. I never get over an hour.
I was a big fan but the more training I do the more I realize that it mostly confirms what I already know. If it says I slept poorly and HRV is low, it's probably because I slept poorly and don't feel up for a big workout. At this point I probably don't need it, but I keep it on my wrist anyways. The biggest benefit I've found is that it can help alert you when things are going pear shaped. If you're usually at like a 42 HRV, and it starts dipping consistently, then it may be time to change something or you may be getting sick or something like that. I noticed my spO2 was dropping and my breath rate was up and it turned out that I was in the early stages of pneumonia. Anyways, I use an apple watch and the metrics are fed into coachcat, but I may dabble in athlytic soon. The apple sensors are the best but apple health doesn't really give you actionable info with their home app. Garmin has usually been mediocre for me (735xt and vivosmart bands) while fitbit was actually really good (luxe was a nice compact band).
