If you are going to mic it and put it through a PA in a rehearsal space, or jam room, then get the straight. If you are going to keep it in your house to annoy the neighbors, or are going to use it in a jam room with no PA, get an angle cab. They are very directional, where you stand in relation to it will certainly affect how it sounds, but straight cabs always sound more "bassy". If you put it on a stand, however, and bring it up to ear level, it doesn't sound that way any more. Out of personal preference, I say get the angle cab, if you can't talk yourself into getting both.
