What is the best paintball gun?
The "best" is a matter of opinion, because at a certain price range, the only difference to be made is ergonomics and valve type. This is because speed is limited by how fast a loader can feed, accuracy is limited by the barrel to paint match and distance is cut off at how efficiently you can shoot at 300fps. At a certain point, when looking for the newest and most advanced marker, they all operate at near identically the same level. Since everyone's hand shape and size are different, the "best" gun is that feels the best to them. This includes valve type, between spool and poppet, which feel different when shot.
