It's free, it works very well with Maya (which I use most of my time) so there are no problems if you already know how to work in maya or any other software like zbrush etc..
The only thing that might be better would probably have more options when working without hud as sometimes i do not see what buttons does exactly which function but its still possible just try out different settings! For me this has been one step closer towards using less plugins instead having them all installed separately from programs such us ZBrush/MayA ect...
