They both do if you are rooted. I actually used Apex over Nova free versions. I think it was because I couldn't get my simple text to work on Nova but that works now. The purchased versions of each, it appears that Apex has more features but I prefer the purchased Nova over purchased Apex. Why? Only for the simple reason that in Nova I can organize my apps into folders in the app drawer, where those folders are visible when I open the app drawer. In Apex, organized app drawer folders are not visible on the app drawer screen. I have to select the folder I want from a drop down menu in the app drawer.
Another advantage of Nova is that hard pressing on home screen for your widgets, you can actually see the widget text.
