I just upgraded from a Garmin FR 235 to a Fenix 5 Plus. It is a HUGE jump in usability. One of the biggest for me is the pool swim activity. I go into an almost zen like state when I swim and lose track of how many laps I've done, problem solved with the 5 plus! I can make workouts for a swim or a run and not worry about spacing out and forgetting the program. The battery life is great, about a week and a half with 5 to 7 workouts actively tracked during that time. There are some really good deals out there on the 5 plus which is nice. I was looking at getting the Fenix 6 but the cost difference is crazy!
