I use Komoot, but it’s targeting a different audience than Strava. It’s a great app for bike touring or route planning, that sort of thing but it doesn’t provide ‘performance’ metrics like Strava. It’s not about leaderboards, comparing with other riders or setting personal records, it’s much more oriented to the adventure or touring crowd. You can see routes others have ridden, but the pace at which they are ridden is very much a secondary concern. Komoot is excellent for route planning, and I use it for that quite a bit. It will work just fine for recording your rides, but if you have a Garmin device you could just use Garmin Connect and not bother with any additional software.

As to the topic in question, I’m someone who quit Strava and didn’t go back. But, I’m not very interested in what Strava provides, I joined only because an annual charity ride I participate in couldn’t hold a mass start during the pandemic and it was how we logged our solo rides instead. Once we went back to in-person I quit Strava as it doesn’t interest me at all.
