I got to use briefly some iphones starting from 3GS, and honestly, I like how smooth they feel in day-to-day usage, but the biggest drawbacks for me is absence of full featured adblocker (ublock origin), itunes hassle, and no alternative way to install apps (app store only). I also consider my phone to be a pretty dumb tool, but I also occasionally browse web and do banking with it, so I'd love to use iphone if Jailbreak wasn't so fragile. Instead, I have to set the phone aside myself from the scratch :)
