It's one of the better launchers. Try out the free version for a couple weeks, and if you like it, you'll definitely want to spring for the paid version as it gives you a bunch of useful options like gesture control. Apex is nearly identical to Nova (feature wise) and is another great launcher option.
Another Nova user. Also got paid version.
I like how you can remove the padding on the home screens. The choice of screen animations. And gestures for hiding the different trays.
