I think what he meant was that the gun, in certain circumstances, means nothing.
A kid with an Angel or a Cocker, who can't aim, and has no tactics, will be easily beat by someone with a Tippmann or Spyder.
Tippmann's are good for recreation, but I wouldn't recommend them for tournament play. Seeing as I am only 17 years old, and play maybe 15 times a year, my 98C is doing fine.
Oh and FFMCobalt, I am sorry to hear about your bad experience. People like that are ridiculous. If you know you hit the person, and you see the paint, you don't need to keep firing just because the ref hasn't seen it yet. This is why I don't play at a field, but rather with friends of mine who I trust not to be jerks.
