If LTE isn't a huge deal or you don't live in an lte area, get the international version and hop on an unlimited data plan. The speeds have been great and it's only $15 a month. I called and got mine on today and it was a lot easier than I thought.LTE isn't a priority feature for me. My wife has the AT&T variation of the SGS3 (with LTE) and while I freely admit that her data speeds are (at least) 3-5 times faster than mine, it doesn't matter...
Sure, LTE is awesome for the speedtest app, but I've never had issue with non-LTE speeds (unless the phone has a poor signal, in which case I wouldn't be holding an LTE signal either.) Web browsing, push email, tapatalk, and everything else _I_ do on my phone feels just as fast regardless of LTE or not. There's only been one time in the past 2 months that I wished for LTE - and that was when downloading something huge from the play store when I wasn't on wifi. In that regard, for my usage, LTE is actually a negative as it drains the battery faster. (How much battery drain is a debate that can be saved for another thread.)
Of course, LTE might be much more valuable for other people.
The only way I'd take the AT&T LTE device over the international (non-LTE) would be if I got the LTE device for 300 or less, and if the AT&T phone wasn't crippled/downgraded the way a few other samsung devices on AT&T have been. (Huge example being the original Note.)
Yes, I'm paranoid... and with good reason.
