Which phone version should I get?

[EndgameZ]

Hello everyone,
I'm planning to buy an LG G2 for an upgrade over my Moto G, but after doing some research I saw that there are two different versions of the G2 that I can buy, the D800 (AT&T) version and the D801 (T-Mobile) version. Both versions are unlocked, so I was wondering if it made a difference if I chose one over the other.

EDIT: I forgot to add that I have T-Mobile at the moment, and even though it would make sense to get the T-Mobile version the phone is a decent chunk more expensive than the AT&T version. So just wondering if I'll run into any problems switching over.

The models should be the exact same specs just branded differently, check to make sure the cellular technology the phone runs is the same as the carrier you are using.
