They are all a bit threadbare on the facing IMO (like most U.S. aftermarket wheels are for some reason - perhaps for weight reasons). I like the regular OEM CX-30 wheels a lot better than any of those. I personally prefer a bit more alloy meat on the actual wheel design so that you can't see the entire inner-workings of the wheel/brakes behind an almost non-existent design facing. For the CX-30 & it's thick cladding, I would also want a wheel design that had a good amount of black or dark gray in it. As a quick off-the-cuff example, something like the one below I like a lot better than all the designs that you presented:

My 2015 Yaris SE Hatch had the design below, & while a bit funky looking, it actually looked good on that vehicle:

This the the dark gray 18" Mazda wheel that I wish they would have used on all CX-30's. I'm pretty sure I have this same wheel on my Carbon Edition, except in darker gloss black (like the turbo versions also), and the other non-turbo trims have the silver version of this as well. It's an attractive design though, regardless.
