I've been pretty happy with my Garmin Instinct Crossover. It looks like a regular watch, and so if Garmin decides to drop support for it, then it still has like a 2 month battery as a regular watch.

fwiw I bought a two-year old Garmin model on clearance like 5 years ago and they continued to support it all the way up until I bought an Instinct 2 this year. So I think you’ll be happy with the support you get.

With Gadgetbridge they can drop as much as support as they want.

Gadgetbridge has very limited aGPS support, right? Without aGPS updates, any GPS device is going to have terribly long lock times.

Ideally, watches should do like Garmin's. Mount as mass storage devices via USB, and let the user download activity data and upload updates or routes.

For my Instinct 3 Solar GadgetBridge it - as far as I can see - can deliver AGPS files.
