Like St. Anger, God Hates Us All is only enjoyable to listen to if your really angry with the world. XD

As far as metal bands I like:

Black Dahlia Murder- Saw them live. They are amazing. Great Drumming. Bad vocalist IMO but whatever.
Lamb of God- Saw them live as well. Best Metal Concert I've ever seen.
Children of Bodom- Do I have to defend CoB? They are amazing.
All That Remains-I love their style. Very Lamb of God-ish in guitar riffs and very catchy.
Amon Amarth- Again, a legendary metal band. No explanation needed.
I'd say Avenged Sevenfold is metal. Even though they are more mainstream, like disturbed, I'd still classify them as metal. I can see your argument though.
God Forbid- Their songs are hit or miss. I love War of Attrition and Empire of the Gun but others are "meh..."
Kalmah- Very Children of Bodom-ish. If you like CoB, you'll probably like Kalmah.
Pantera- Duh. If you like metal, you have the love dimeback.
Slipknot- Though mainstream, I loved their new CD. Joey is still an amazing drummer.
And lastly (and probably most debatable to be considered metal but my absolute favorite band) Dream Theater: I can totally see the argument that "They aren't metal but progressive rock." However, certain songs are VERY metal in my opinion. A Nightmare to Remember and This Dying Soul are examples. Dream Theater is without a doubt the most talented band ever (Minus their singer XD.) Petrucci, Myung, and Portnoy extremely talented and them staying together in the same band for 20 years is really great. If you care about Music Theory and song writing, I highly suggest you listen to Dream Theater.
