I think I like the 12 Blue better than the Pacific blue. But I’m honestly kind of wanting the access to the Apple RAW photography mode on the pro models. I originally was going to keep my 11 Pro and trade my SE in for a blue mini but the presentation threw that little surprise my way.
I think the high gloss and deeper shade of the blue on the regular 12 is a little bit prettier than the one on the Pro. But it is hard to tell unless you see them in person which look is really preferable. Bolder looks photograph a bit better tha more subtle ones.
