I'll have to take a look at those. Have you every tried Nova Launcher? I just looked at screenshots of Apex in the Play Store and read the description. It seems like the functionality is just about exactly the same. They both have a free version and a pro version. It looks like the app drawer works identically. I much pretty dark themes myself too. Especially with the active matrix on the new AMOLED screens, they don't have to use power to display black pixels, as far as I understand it.
