Cant decide which laser to buy

[laser person 69]

Hello, I found these 2 cool lasers on laserpointerstore.com and can't decide which one is better:
1. 450nm 1600mw Thor M2 for $50
2. 520nm 300mw for 65$
Which one would be better at reaching far distances? Would the dot of Thor M2 laser still be visible on the buildings 6km away? Which variant is better when I don't care about the burning abilities?

Hey buddy, I own a Thor H2 3w and a 303 green laser.
From my experience, even though its not the same laser, Thors are great, very fun to play with mainly because of the power.
If youre just aeeking for distance, from my experience both of my lasers reach almost the same, altough the blue one has 2x the power, so probably the 520 nm will be more visible, but the Thor has much more burning capability
