What's your preference and why? I've tried both. I liked Screebl, but I kept hearing how it drains the battery. I'm currently using Keepscreen, but basically when I chose which applications I wanted KeepScreen to work on, I realized that it was mostly all the Apps I would use on a daily basis, so I figured if the screen stays on for all the apps I used, it basically becomes useless. So what's your preference?
