Well personally, if money is no worry, i would pick whichever one I was most comfortable, I've shot some amazing proto's, and ive shot some **** ones too, i have to admit i personally do not like Ions, although hats off to smart parts for releasing the marker (it is good.) I just dont like the feeling of them. Rather than ask advice as to which one to get, I would shoot both, and then present the question such as "I can snap shoot great, but dont like the trigger on this gun, and I can walk the trigger and snap shoot, but the guns quite heavy." This way, you can get a gun thats good for you, i shoot an impulse, not because I think its the best gun, but because its the one I perform best with.
