Yes, good goggles are a must. Check out the offerings from Survival Lasers for a good set at a reasonable price.
Agree ---both are extremely dangerous --goggles required---all things being equal if the only choices are 1W or 7W exposure--1W is less dangerous than 7W in a few ways is what I meant.

If long-distance pointing is desired, then beam divergence and shape should also be taken into account.

Color is a matter of personal preference. 450 is kinda purpleish, 465-470 is nice, ligher blue. 520 is essentially definition of green.

I myself prefer beam specs over power, as there is already plenty of power available.
