I have both led and gi ocd boards in all four of my older games. Makes a huge difference to me. Games look more fluid and natural with all the benefits of leds. You also can tune the brightness. I did that on my FH I just finished up. Inserts were way too bright for my liking so I turned them all down. Some larger inserts needed a little more brightness so I adjusted those. In the end, I got everything exactly like I wanted with all the fade effects and no ghosting.

I don't think you can run non ghosting bulbs with these boards, though. They will prevent fading effects since they are designed to only turn on at full power.
