Which Tippmann should I get?

well i bought a tippman a-5 and my bro got a 98 custom, i kept having problems with my a-5 but the 98 customs are very reliable and east to maintain, i would strongly reccomend a 98 custom all my friends started using them as a beginner gun and they never had and issues with them. im not sure about the other 2 types but i think the 98 is the way to go
