I can't say I've been 100% happy with the LEDs I've tried, because the tend to reflect off the screen in a very annoying way. In fact, to change the subject a little, my #1 complaint about the eDgE is that e-reader screen: I guess because of the touch-screen thing they have to put on top of it, it's rather less readable than a Kindle's, plus it's shiny and picks up troubleseom reflections. A fault of the technology, not the design.
