Garmin's cycling computer user interfaces and bugs suggest those groups don't employ product managers who are active road cyclists.

Finishing long rides quickly requires being smart about pacing so you're fast and navigating well so you don't add extra miles; although Garmin won't give you power or heart rate on a navigation screen, and requires a complex menu dance to move between course and non-course mode. The ELEMNT includes up to 4 data fields on the map screen. The Joule GPS does 2, although it's breadcrumbs only without maps. Cellular phones do fine, although mine ran out of battery when I used it to drive to a ride, and I was down to 15% when I left it in my pocket on a 9 hour ride with ridewithgps running but display and GPS turned off when unneeded .

Riding intervals the time is fixed and you only care about power and/or heart rate, although ending a lap on the Garmin only summarizes time.

My Edge 500 has always had bugs a serious cyclist would encounter, even with the final firmware version shipped years after launch. When I calibrate my PowerTap before riding but deal with other things long enough for it to sleep my Edge gets stuck on the calibration screen until power-cycled.
