Between the Buried and Me is YOUR FAVORITE band of the last 10 years. They're clearly not the best.
Also, @ML- Devourment's vocals are great... especially when done by Ruben Rosas.

As my good man rabid would say, metal is a cheesy genre in general.
Maroon
Through the Eyes of the Dead
Older Norma Jean
As Blood Runs Black
Despised Icon (Deathcore, but still)
Hunter-era A Life Once Lost
Impending Doom (Deathcore, again)
Lyrics about Satan are as Metal as it gets, you two bit pansies.
Those are just the better metalcore bands I know of.
