I'm really undecided about screen size. I love the looks of a larger screen and it definitely has its uses. At the same time though, I also think, it is just a phone. I'm mostly going to text, make calls, check facebook / twitter, listen to music, and occaisionally look something up on the web. Do I really need / want a huge screen for that? I could always just whip out my iPad if I'm looking for a larger display. I also thought, well 4g is probably awesome, but, I'm rarely in an area with 4g coverage, but am mostly always in an area with wifi access. Usually when I'm not in access of wifi is when I'm driving, and obviously I shouldn't be using the phone then anwyays aside from navigation / music, both of which have never given me an issue with 3g.
Widgets are pretty meh to me. The only one I've consistently kept on my home screen is the power control widget to turn Wifi on and off as it feels to me like my battery is better if I only turn Wifi on when I'm going to connect to wifi otherwise it is constantly searching for Wifi.
Either way, I think either phone will do what I need and both will do it very well, its just going to be about size / feel.
