Yeah, they're pretty good, their only full length (the first 12 or so songs on their 2-disc set) is REALLY good, the rest is decent. The guitar playing is excellent. Loose and sloppy but somehow precise and usually pretty jazzy.
I wouldn't say at all that they're "underrated"; they're extremely well-known and considered influential by many artists... not as well known as the offshoot bands like Joan of Arc (which has some interesting stuff) and the Owls (who are kinda boring)... but definitely more well known than Make Believe (who has some of the craziest guitar lines I've ever heard!).
