Well, I would keep the X. I recently purchased a new (used less than a week) TB from a friend and it seems to be a nice phone, but the battery life really sucks. So, I fixed it up for my sister and she has it now, she switched from her X to the TB and kept her X. She has offered to give it back to me because the battery life sucks...even with the extended battery. She recently went on vacation and went through several locations that actually had 4G and that has at least for the moment got her keeping it.
But I had/have the chance to get it at anytime, but I am just not interested. If battery life was better and there were more 4G service areas or if I lived even remotely close to a 4G area I might think about it, but think is probably it for now
