I'm certainly no expert, but my vote is for the original A5. I bought one with the GTA E trigger when they were first released after taking an extended paintball hiatus. once you open the valve tube all the way and use the hammer spring pressure to set the velocity, they are very nice to shoot. I think the early A5's were the pinnacle of the Tippmann line. Admittedly, I have never shot and ICD, but the comments here are seriously threatening my bank balance, actually maybe not so much, I have never seen a vert feed ICD blowback.
Runner up for me would have to be the Bob Long Millennium.
