Not considering the mini. I left an 11 for the SE2 to try something smaller (was just missing smaller, lighter phones) with the plan to use it til the 12s came out. I loved it - still do love a LOT of things about it - but typing on it, even in zoom mode, was just not cutting it. That eliminated the 12 mini from consideration.
Honestly, the weight of the 12 is much closer to the weight of the SE than it is to the 11 pro (which I also considered), so I’m pretty happy with that. Holding them both, I really can’t tell any difference, and I could definitely feel a difference with the SE2 and 11 pro.
