15 Pro
I think this is right? The 8 was the first "big" iPhone I got, having resisted the 6 and 7 models in favor of the SE. I just hated the idea of phones that were a big departure from the easy one-handed fit of the early ones. And when the Minis came out I got both of them in turn. I finally buckled and got a 15 Pro because the battery life on the 13 Mini was just really hard to live with. Been very happy with it, though I still find it awkward to juggle one-handed and bulky in the pocket.
I still actually have my SE 1st gen. sitting here in a drawer, and every once in a while I power it up and am kind of blown away by how tiny and compact it is. What I truly truly wish is that the phone carriers would let you activate a second phone with the same number. If that was the case, I'd definitely keep the SE activated and pop it into my pocket when going out for an evening, taking a walk, stuff like that.
