Had serrated steel rims on an old Peugeot. Wet weather braking was scary. Dry weather braking was just noisy. The serrated rims also ate up brake pads pretty fast. For disc brakes like the OP has you don't have those downsides but I'm not sure of a reason to choose stainless steel rims unless you're going for a particular look or period correctness.
