It depends on the quality and size of your paintballs.
They do not, mainly because of the tolerances for paintballs themselves (it will burst when exposed to exploding gunpowder) and the size of them (the average size of paintballs are in the .68 caliber area), unless if you're talking about Simunition (in which this type of projectile is restricted to the members of the armed forces and law enforcement officers).
They are actually one in the same. There was never an orginial "model 98" only the custom series. The difference though would be found in the Tippmann 98 custom Platinum series with its easy to remove body. There is also a difference in barrel sizes if im not mistaken but I think the newer 98 customs and platinums have the improved size (the same size as the A5)
