Love 'em.
I'm a big Allan Moore fan, and I've pretty much gotten everything he has ever written. My favorite comic of all time is From Hell.
I read lots of other stuff too. Lately I've been into "funny books". Meaning, comics that are funny (obviously). I usually read more "serious" comics, but the funny stuff has really been getting me lately.
As for comic strips, for me there can be only one: Bloom County. And I can't express how much it pleases me that they have finally released all of Bloom County in chronological order in the volumes of "the Bloom County Library". I would recommend these to anyone, but especially to people who grew up in the 80's and early 90's.
