I had the iPhone 5S (64GB, Silver) for a week (sold it for profit) and until you try/used the Touch ID (finger print scanner), unless you're a fanboy I don't know why you wouldn't want it. I don't use Password/PIN, it's a PITA to deal with but Apple made it so effortless.
Honestly, I almost bought the 5S (16GB) as my second toy to my LG G2 because I previously posted I was sick of Samsung & the Galaxy line up but I've been spoiled by Display & Battery Life.
I hope Samsung is reading this thread. Great idea!
As for OP. Speakers. Spoiled by hTc One.
Having two Super Phones, I want all to have EXTERNAL (micro) SIM SLOT like the LG G2.
