So, I think this phone looks great, but I'm not buying into LG's UI, it looks so cluttered. After using Sense 5, and looking at the notification bar on the LG I really do appreciate how much better it is to have the Notification Bar, rather clean (minus the power saver, bleh). Not a big fan of the unlock screen, the icons and everything look dated, they remind me of the GS2, instead of the GS3/4. Plus I've been spoiled by the ONE with it's great sound, camera, and construction. Other than that, I think the power button placement is genius, honestly. I have never minded power button placements, they have to go somewhere, but having it in the back makes them much more easily accessible.
