That's pretty much any discussion where someone asks an opinion. "I bought X, so therefore you should too."
@SpartaBard The glitch issues with the Garmin head units don't seem to exist on the current units. They had issues earlier with the touchscreens sucking, that seems to be resolved. And even there, if not trying to use the maps the buttons of the 530 seem more than OK. Also a lot of issues people have is with early firmwares, Garmin definitely released stuff too early.
While there may be pluses to the Wahoo head units, it is a different ecosystem. I'm all-in on Garmin so I'll pay a little premium. Plus Wahoo doesn't have watches to compete.
And I could be wrong, but I think the Wahoo mount is basically the Garmin mount, mounted 90 degrees off.
Check with your insurance company, you may get 20% off Garmin or Wahoo products.
