RA MaxX - Consistent. Very high potential ceiling, but difficult to pilot well. Has some difficulty in the current meta with CVS being popular; I think that might be dropping off, so it may be better in the near future. No real changes since Net-Ready Eyes came out. The best of the three in my opinion.
Eater MaxX - I don't like Eater as a breaker, high install cost and high breaking costs for many popular ICE. Anti-AI ICE can pose problems. Can potentially lock a corp down and then out with Keyhole, Siphon, Apocalypse, and other cards that give the corp a hard time.
Mihn MaxX - Takes a little while to set-up to safety if the corp can get money early, typically through burst economy. A quick remote play with aggressive agenda pushing can get out points quickly before you can respond. The fastest of all DLR set-ups. If you can control the remote, any non-FA corp will have extreme difficulty winning the game, if they're even able to.
