well at a glance one is black the other is brown. one is a single cut, the other is double. I feel like unless you fingers are just freakishly long, you wont be wrapping your thumb over the top of the neck down at the heel anyways....

I declare this battle to be one of aesthetic preference.

One's got a double cutaway, the other one does not. Aside from that I think they'll pretty much sound alike. Try them both out, pick which one you think sounds better.
hmm also, the G5120 has an included $100 gift card included... I'll have to officially check them all out
The 5122 is thinner than the 5120, as well.
