Well they are pretty much the same length and both are meant for CQB if you want to be tacticool get the UMG
As it has the rails in the front to add a flashlight and laser, believe me a bright flashlight is very useful for blinding people in CQB, though it gives away your position if you use it correctly it works. I can't count how many times I saw a bright flash and then BBs hitting me.
I also see you wanted a Thompson if you have not test fired one already I highly suggest you do it. Its a interesting gun to own but I found the MP5 and UMG to be of better use, with sighting enemies and rail attachments.
