Is there a Pebble Replacement Underdog Smartwatch in 2025?

I'm not really a watch person, but if there's one watch I remember positively, it was my Pebble back then. And somehow, I'm currently feeling like getting a smartwatch again as an incentive to do more sports. Is there currently an "underdog" out there, a worthy replacement for the Pebble? With today's technology, of course, including features like heart rate monitoring, etc.

Thanks for helping.
