I've been reading that fords stock Intake performs very well and a CAI is more looks and sound than performance. For those who have a quality CAI are there noticeable power differences between the two with a tune?

At least until you start adding in things like ported IM(s550 upper with s197 lower), headers, etc. That being said, the only intake I'd use is steeda because it has a larger tube and maf area making it tune required.

That is not totally true. If the manufacturer goes through the time and expense to get a CARB exemption it is legal. Airaid is one of the companies that get the exemption.

Also, a lot of cars come from the factory with CAI, the Shelby GT350 is one.

I purchased the FP Performance Pak for my 17 Ecoboost Mustang and it came with a CAI (same one as the GT350). The tune and CAI are EPA certified and they give you a sticker to put on the CAI with the Executive Order number to show it's compliant.
