I don’t have a horse in this race. I’m not on the Rapala Ice Pro Staff and have zero affiliation with any electronics. Just simply what I use and what I am very happy with.
I’ve ran both and in perfect conditions, not much difference. Get into lower light levers, stained water, or deep water, and Marcum will shine.
As for color – if you have enough light, the color will give much more detail at a glance. When the light level drops, you’ll need to go into a gray scale regardless. Like any video equipment, you need to have realistic expectations. The Marcum 625 & LX9 have far exceeded mine and I’m a picky SOB when it comes to details.
Here is a couple samples I did with the LX9 (same camera head as the 625) You’ll want to jump around in the videos and check out all the conditions I recorded in. I think over-all they are a great set of samples for all negative conditions. Nothing like the super clear water James was recording on up at Green Bay.

18-22 FOW off a wing dam – perch, walleyes, sauger (all butt faced) This video is a little shacky because the ice is going up and down with the wind. = http://youtu.be/vyQPLqWZICA
