I've been trying to decide this for a long time (since august) and I decided macbook. If you need firewire that bad then go for the macbook pro. Also mac can run windows. And lastly, macs are not better then pcs and pcs are not better the macs, its just what you want to do with it.
It depends if you want to go in at close range or farther range. If you want to hit someone over 20 feet away get a BBB and mod it. If you want to want to know your gonna hit the person at close range go with the vulcan. If I were you I would pick a BBB. My vulcan broke the second day I had it. Also you can get a rapid fire tommy 20 with the extra money.
