The A5 Is the best out of these mentioned, even wi price considered. It is the same price as a alpha black (bravo one in Canada) and a cyclone feed, but is easier to take apart, has more upgrades available, has a tombstone adapter instead of the plug or screw in vertical adapter.
The X7 (non Phenom) is just the A5 with more plastic parts for more money. The Tippmann X7 Phenom is a superior marker to all other Tippman's because of its Spool valve and ability to work semi automatically without a battery and fully automatic with a battery.
