I think you are looking at this the wrong way Legionaire. The Grey Knights fight not only Daemons, but also those that consort with them. They are an Anti-Chaos force. Having said that it is not fiar to say that they would be unable to fight non-Chaos opponents. Lets look at the facts. Overall abilities as a military force:Grey Knights as Astartes make for better soldiers in general due to the nature of Custodes work. Powerful Psykers, superior equipment and much better willpower. Not to mention centuries of combat experience. The Custodes have not left to fight offworld in nearly 10,000 years, with the incident on Pluto being the most recent. Anyway you cut it the Grey Knights are a superior force.
