Which device is correct though?
Not by much, like yesterday my speed avg was 17.9mph for 45 miles according to Cateye's and Garmin's
had it at 17.6 mph. So what gives?
The wheel size on both devices were entered as the same.

PS Both my Catteye and Garmin are mounted on my bike. Left the Astrale on to test the accuracy of the Garmin.
Actually, Corsair . . have a look at the time and distance on both units for that ride (which generated the average). That will help diagnose where the diff is coming from. Is the time longer on the Edge and distance the same . . or the reverse . .or are they both different?
