Which forerunner is closest to the Fenix 6s pro?

So I basically had it with the Fenix, and especially the pace/distance/accelerometer issue. It's totally useless for running, and especially for a Garmin coach or any other structured running programme. Tonight there are intervals on the plan. How the heck am I supposed to do 30 second intervals if it takes more than 2 minutes for the pace to finally catch up in some circumstances?

Want to see if Garmin takes this piece of junk back and replaces it with a Forerunner. The question is: Which watch is closest to the Fenix? Like running, hiking, pool swimming, cycling. Like all the lifestyle and sleep tracking. And I want a similar, if not better battery time. Shame they don't seem to come with the battery saver that I use during the night. Don't care about music, LTE and stuff, but mapping/routes is a must, small watch. Don't need always on screen. Damn, but I really like the standard watch face of the Fenix! Most importantly: Pace/distance does work!
