I actually really loved the Tales of the Slayers and Tales of the Vampires comics. Still, I'm not sure I'll be interested in anything sans Spike. If this had been a year or so ago, I would have been freaking out over the comics (probably in a bad way), but right now I feel like I've got enough distance to just not care. For me, the show's canon is the show's canon, and the comics, even Joss comics, don't really affect it.
