I'm an Athens staffer so you can take my opinion for what it's worth.
I recently got an Athens Exceed for my 3D rig. I'm really impressed with it so far. It has a very smooth draw, but it's not as smooth as say a Mathews Prestige. The back wall is rock-solid, mainly due to the dual draw stops. I feel that it's balanced relatively well. I've shot it quite a few times already and I'm as accurate with it as I have been other bows. All in all, I'm really satisfied with mine so far.
Athens is a relatively new company but I feel they're making some big moves to stay in it long term. I've never shot an Acccomplice but I have talked to people that own them and they will give me honest reviews. None of them had a negative remark about their Accomplices. Very smooth, great back wall, etc. It's a binary, so it builds up a little quick like they all do.
From everything I've heard about them, the warranty at Athens is top notch. If you have any other questions about the Accomplice, or Athens in general, feel free to shoot me a message and I'll see that it gets answered.
