Before saying that the engine is "one of the best" or even giving my 2 cents, I'd need to work with it some.
It does look visually up-to-date with the newer next-gen engines, but it could have crappy performance.
Take Unreal Engine 4 for example, I work with that quite often and I know it's a great engine to work with.
With this engine, who knows how it honestly is.
