I find it comfy, but the gameplay takes some getting used to. It's more in-line with something like F-Zero or WipEOut than Mario Kart. It has a really solid singleplayer campaign with a shitton of unlockables and secrets, though, so that helps the adjustment.
I'd suggest you wait until they release 2.4 since that's supposed to be a semi-overhaul to the item and ring balance (rings being something akin to boost fuel in F-Zero), so it'd be better to get used to it once that's implemented.
