The red is obviously going to be better for burning and such things like that because it is a higher power although the green 100mW will be more visible than the 200mW red. So really you have to make a decision. I would go with the green for the beam and the wow factor.
Also keep in mind both lasers are powerful enough to cause eye damage so you should always wear safety goggles.
And I am not sure where you found those lasers but you can get the same power for cheaper on other sites if you want to save some money.
Hope I helped a little with your decision.

Lazerer is a well trusted website here on the forums just click the power certificate option when you order. They will test your laser for you.
