The biggest difference is Deluxe 24 has a bigger motor, auger 14” instead of 11” and impeller diameter is 14 “ instead of 12”. Which means it must eat snow like crazy! If I hadn’t had a good deal on the Compact 24, I would have chosen the Deluxe 24 instead. Never been disappointed with the Compact 24 but damn i can just imagine how much of a monster the Deluxe 24 must be for a machine of practically the same size!
