Tippmann 98 Custom, Tippmann A-5, Smart Parts Ion, 2 Smart Parts Shockers. Tippmanns don't compare to the speed of an Epiphany. Stock Ions are not as fast or as accurate as Epiphanys. No ion trigger is smoother than the Epiphanys. Epiphanys don't chop balls like the Shockers and are just as fast as the Shocker. Epiphanys are less as expensive and just as good as Shockers.
Regulator isn't very consistant untill you use it for a while.
The Epiphany is similar to the Ion. The Epiphany is all what the Ion should be and should have been. The Epiphany has almost everything that you would want in a high end stock gun, with out the high price tag. Everyone that gets an ion wants to buy a different barrel, get an ASA and drop, smooth trigger, body kit, feed neck, bolt, and put as much electronic crap into the grip frame as they can. Smart Parts saw this and came out with the Epiphany.

What more can you ask for.
I have found this gun to be very reliable and have had only minor problems with o-rings that were easily replaced.
I think that the Epiphany is great! While I used to be popping balls and squeegeeing with my Shockers, while using my Epiphany I never have to even take a squeegee out on the field with me because I have yet to break a ball. I have never been any more happier with a paintball gun than I have with my Epiphany. Because the Epiphany is so light, small, fast, & accurate, I have found my opponents in the dead box in a short amount of time.
