I think those two are best options out of the current lineup. I don't think regular 12 adds anything to the mini other than bulk (and price), so if I would want a bigger/pro phone I'd definitely get the max, which really look epic, almost in the way first generation Galaxy Note I used to own looked at it's time.
But since I don't need (or want) large size, it's mini for me. A bit bigger than the original SE that I currently own, but still good and the difference in screen size is pretty significant (especially compared to the new SE/6/7/8-series design, which are mostly just bulkier).
Oh, and I love how wallet is exactly the same width, looks great, I think it's the perfect minimalist combination.
