I have the wahoo tickr and also the Garmin hrm tri. Both work fine and use them for different things. Wahoo for zwift running and Garmin for everything else as it is so comfortable.
I am one of the people who has used a hr strap for so long and look at the data afterwards to see how my fitness is progressing. I mainly use rpe during my workouts which to me has helped push more instead basing everything on hr.
