Which phone should I choose?

Voted for S3

i have one thing to say.. NEVER EVER GET LG! xD i got a lg phone once and it broke 3 times in half a year, then got a new and it broke before a week had passed.

SAMSUNG GALAXY S3

I would say SIII, and that's what I'm gonna buy most likely in the near future, because unlike the One X you can insert a microSD card, which I'd use to store my music.

The SIII of course.

Banana Phone

S3

S3. If you really want to get a phone without SD card slot and replaceable battery just get an iPhone.

I've been using the S2 for a year or so, pretty happy with it. Prefer it to the iPhone I had before. Thinking of a new one myself. Initially thought about the S3 but now thinking the Note 2 looks pretty good. Also read good things about the Butterfly.
I don't think the Phablets are much bigger to be honest.

Go with S3

Get the s3 i have a 2 note which is kind of similar and its great

OP, you did an excellent job with the breakdown of pros and cons. I liked this thread. Voted for the Black One X. I'm a big believer in build quality.

Edit: SHIT. Discount my vote. Didn't realize the black one was HTC. HTC battery life sucks a big fat cock.

S3 :D

I would get One X, just for HTC Sense which is pretty cool. Samsung's Touchwiz suck donkey balls.

And im saying this from my personal experience as i own both HTC and Samsung devices.
