SVUI was good but he's too slow about updating and doesn't communicate with people. Not having it the first few days of 7.03 was my final straw. Also It takes FOREVER to get things customized right. God help you if you have to reverse your keybinds on a naga to work proper with a 3x4 grid bar too. It's not impossible, just not super user friendly.
Moved to LUI now which the only problem I've had is getting the TPS/DPS docks working properly.
