I have never experienced the flicker affect many talk about thankfully because I love non-ghosting LEDs. When it is not overdone LEDs illuminates the field much better than incandescent bulbs. I go all LEDs but choose the type of LEDs wisely so I get great illumination but it's not blinding. I just can't see the playfield or even the plastics well when some machines have all incandescent bulbs in. That said, I can definitely see why some don't like LEDs and think they are just too much.
