I have both and you can't really go wrong with either.
Pros of Reflex (2012):
Eye-pipe - if you get chop (rare) there is a pipe that should clean itself as you play. Keeps the eyes protected from paint.
Lighter than the axe
Spoolie so it shoots super soft -not a whole lot of felt recoil
Shares many of the same parts as the DM
Hyper 3 reg - arguably one of the best regs out there today
Pretty good factory trigger
Factory 14" two piece barrel, which is pretty decent
Back cap can come unscrewed leading to pressure loss if you don't tighten it every once in a while.
Little heavier\temperamental on maintenance - I do clean/re-lube after every day of play regardless of marker, so doesn't bother me. But it's easier to over lube this gun and get bolt stick/inconsistent FPS
Less efficient than that Axe
Great factory trigger - one of my favorites
Also pretty quiet, almost a toss up between it and the reflex - add a boss/lurker/etc bolt and run at lower pressure and it's probably quieter
Awesome flip switch on/off ASA
No eye pipe - not a huge deal, but having one is nice - cleaning the eyes is a little more involved - but chops are rare - so I wouldn't weigh this too heavily against the axe, but the reflex DOES have an eye pipe.
Factory barrel - it shoots fine, but only 12", I prefer 14"
Factory box - for the price I would have really like a nice case to carry it in, instead of a box.
Non-user servicable reg - while you CAN work on it, it's nowhere near as easy as the hyper 3 reg, and it it will void the warranty
Ergonomics - hesitant to put this here, they aren't BAD by any means, just not as good as the reflex, the banana foregrip takes a little getting used to
Both guns are extremely common so it shouldn't be hard to find someone at a field who can help you out if your gun goes down. If you can go out and shoot each to see how it feels that'd probably be the best thing. You really can't go wrong with either gun. Let me know if you have any other questions.
