It depends which one is easier to get. Which would you recommend.heya , u might wanna think about wat ur gonna be using to power ur new little beast. be it CO2 then go for the tippmann, if uve got access to air then go for the ion. also if ur playin on a recball site u might wanna check to see if they will allow the ion as it will shoot soooo much quicker then most site guns. hope this helps
