In that case, you may want to ask them directly (support@), rather than here in the community forum. You shouldn't expect a response (here or directly) until a few days after the MUM is over, though.
As for your dilemma, either box should handle it just fine. With so little detail, it's tough to call one or the other 'better'. If simple routing is really all you will be doing, I would go for whichever is cheaper.
