I've seen a few ColorDMDs in the wild. FT, MM and I purchased DW for my machine.
I can't really state which title does it better, but I can state that I REALLY enjoy the color on DW as a player and a watcher.
Furthermore having the DW Moving Dalek Topper AND the DW ColorDMD... I find the ColorDMD a better asset to the game. I see it all the time and the colors selected by Shimoda feel perfect.
I really don't have a huge $$ to invest in games. I love pinball and ponying up $400 for ColorDMD took a LOT of justifying. But the second I had it installed I NEVER looked back. I wish I could say that about all my purchases.
Again, don't know what's best but if you love Doctor Who... you will love the ColorDMD dots (oh, and yes, I like the dots).
