Like many other products, there is a learning curve but once learned, (and both will need to be learned) it comes down to day to day performance once everything is setup. That is why the complaints about the Garmin being harder to setup do not matter much to me. For me, the Garmin seemed to have more bang for the buck over the Roam and while it seems that the Wahoo Roam has some popularity in forums and youtube, I would guess that Garmin probably sells their units 100 to 1 over Wahoo (just a guess). Also, I have found that the Garmin Connect online platform is great.
