Some pros - pull down interfaces, which are honestly genius, I wish they were more widely adopted by other apps. Zoom out on double tap for easy one handed operation. Easily reachable and system wide back button (instead of per app back button located at the top left). All of that amazing for one handed use.
Multi window, split screen and other viewer shenanigans - rarely needed, but sometimes feel truly amazing to have.
Operating camera with physical buttons (not sure, maybe iPhone also can do this now). Very handy for opening camera, taking picture and closing camera all without literally moving a finger, on the move, in the outstretched hand etc.
Sane keyboard with numbers and special symbols visible.
Probably many other small things we just take for granted on droids.
Should have picked flush fit thyroid instead of the regular lump one. :)
