I have a Wahoo Roam and pay for Strava. The live segments pop up on many of my rides (you can turn that feature off) but most of the time I'm not out to beat my last time anyway - I'm out riding for fun.
When I'm out on a loop I pretty much only do for training/exercise, it is kinda motivating to try to beat my old time. But that would not swing my decision on which bike computer to use or whether to pay for Strava or not. So, it depends on your goals for your rides.
