Apple has serious problems, but on balance it seems to be the better choice. I also tend to agree with the OP that the iPhone SE is a reasonable size, unlike every Android phone on the market. I just really wish there were a decent chat client that supported XMPP-based services, that's really all that's stopped me from moving over (my carrier lets me receive SMS/MMS messages to an XMPP address and receive calls via SIP, so it's rather important to me).
