Has to do with the way the gun parts are lined up in the airgun.
Spyders are stacked, Tippmans are all in one single line. Look at the side of the gun, on the two brands and you will see the spyder is "taller" at the reciever.
I always liked tippman better, but it is like a lot of things that comes down to personal preference.
