If you hadn't already moved to Unity I would've recommended Unreal4 instead. C++ is just a better language overall for game development (imho) and having free access to the engine source just seals the deal. At my first game industry job I learned the tools in two weeks, then was able to modify the engine to support instanced skeletal actors within a few months super easily. It was awesome.
All in all I believe Unity gets more attention than Unreal4 because it was leagues better than anything else for a few solid years, but Unreal4 is better on the whole. If anyone else is looking to move away from Acknex, try Unreal4, I'd be surprised if you end up regretting it.
@Superku has his current project at 95%.
Yeah, for the past few years! Come on Superku, time to finish that thing!
