It's all relative and very subjective. All three of those handsets sound fine to me. Unless you have some specific usage pattern that requires the absolute fastest processor (etc.), why not simply grab a G2x(?)
I'm going to buy a new phone on android.
First I decided to buy Atrix HD but I can hardly afford it. then checked Atrix 4G but found out that it can't be updated to 4.0/4.1. I was told that LG G2x was a good option but I don't know how good it is.
So can you suggest phones with similar Hardware?
P.S. I don't live in usa and I don't care about carriers. I'll have to unlock it.
