No idea about relative degrees of power - but I guarantee you the coilgun is far cheaper, and probably a lot smaller and lighter as well.
EDIT: also, about the lasers - they look doable, but I'm not sure how easy they would be to get as pure hardtech. Where is your character going to come up with the money/influence to buy them? It's not like Northrop-Grumman sells cutting edge miltech to just anyone, and the pricetag is sounding pretty nontrivial - especially since the fact that you don't have a planet as a backstop means that you'll have to field two systems.
It's also worth noting that they aren't offering these as anything other than point defense weaponry at the moment - and that for use against things that are already inherently explosive. They're definately high-quality as far as that goes, but.... Anyone have any idea how much more than that they'd be able to do?
On the other hand, if you're intending that these be a Li Kohran Special, then it's certainly plausible to have a high-quality hardtech point-defense laser system powered by wavetech generators. It still wouldn't be *cheap*, but it should be within your character's means, and it would provide plenty of protection from someone tossing missiles at you.
