At 52, I'm curious about power output, but not so much that I want to switch pedals based on the reviews or pay for the Pioneer crank based system.
That said my unsophisticated setup with a Fenix 5plus, newest gen Varia, cadence & speed sensors has been excellent. Then again I also don't use turn by turn.
It really doesn't matter who's making these things, the more we connect & pair to it the more complexity WE are introducing. Should it all work? Yep, but interop is a tough beast. Toss in the awesome updates that we get in Android & iOS, I'm amazed things work as often as they do.
The best we can do is find something that doesn't drive us completely insane and go from there. Good luck on your quest.
