How do either compare with a cheap bike computer though? Do you find the Garmin is better than the bike computer calculating speed and distance from the tires revolutions?

Garmin does both. You have a wheel/cadence sensor, as well as the GPS. If you calibrated your gsc 10 (wheel/cadence sensor), that will take precedence over the GPS.
I haven't tried any newer bike computers so I can't comment on reliability or accuracy.
One thing I like with my 510 is I can pair my phone with it, and then transmit where I am. When I start, my wife will get an email with a link, and when she opens it, she can follow me. I'm the slow dot on her map. It shows her my speed, cadence and of course location. This only works when you have cell service though. So if I'm riding too far out, like to the end of 66, I don't bother with it.
