Yes extremely, they're both very user friendly and stable programs. You can actually enable pie controls with gravity box (not on KitKat though), but I prefer the full LMT app for its customization. Here are the links to the respective threads:

gravity box link isn't working, but thatks for that. I am waiting to get to kitkat before I unlock bootloader and root to get these things, they look really useful. being able to get the extra screen realestate would be amazing!
