I also did the T-Mobile uncarrier thing. I got an S4 at first but I hated it. Traded it for a 5S. Apple may be more protective but it is a lot better than an Android phone. My S4 was clunky and full of "bloatware" which is additional bull**** placed on your phone.
Apple4lyfe it's so much more efficient and reliable. PLUS we are safe from malware.
Nexus 5 looks nice though. Google keeps things very simple which I love.
