I've used both safari and chrome. I have only used chrome for the past couple of months, but reloading is prevalent, much much more than it did on my iPhone 5. Chrome also crashes quite frequently as well, but typically it is certain sites that crash it.
Sometimes this site causes problems, every once in awhile I'll open a thread and then the touch to scroll is extremely laggy, where I'll swipe my finger up and it will move 3-4 seconds later, if at all. Same goes for all clicks (even back button). I think it might have to do with certain ads.
Oh and the ad thing reminded me, fuck the auto redirect to the App Store ads. I want to murder the fucker who thought of that, and whoever at Apple who decided not to at least have an option to disable it.
Oh and another thing as I type this, typing on a forum like this doesn't automatically scroll to the right when the text I'm typing reaches the screen edge. I have to scroll down on the window slightly, and then when I keep typing it will snap over to where my text is appearing, until the next line where I have to scroll down again.
All in all its a pretty piss poor user experience to browse the web on this thing
