Note that in Star Wars laser bolts are ridiculously slow (perhaps that's why they can travel faster-than-light so easily?) and Spess Marines could probably dodge some of them. Besides, attacked by clones, they wouldn't really have to dodge - just charge in and slay everything clad in plastic armour.
Add daemons, countless Orks, Tyranids, Necrons, Eldars and imperial artillery and, for me at least, it is clear that 40k > SW.
Lightsabers might be all-cutting, but are gay and make gay "bzzz" sound.
Chainsword tear everything, rather than cut, and make "RRROOO-motherfucking-AAARRRR". And it's manlier.
Boobs, That is all.
