*** Awesome ***

Structures - Departure & Transitions
Walls of Jericho - Try.Fail.Repeat.


*** Good ***

The HAARP Machine - Disclosure
My Bitter End - Becoming Misfortune (I like their music, but not the singing)
Katatonia - Onward Into Battle
The Agonist - Serendipity
Nightwish - Planet Hell (I know this band, it's weird, I can't have a straight opinion, I don't know if I like them)


*** Nope ***

Volumes - Wormholes
Intronaut - Milk Leg
Woods of Ypres - Kiss My Ashes
IWrestledABearOnce - Tastes Like Kevin Bacon


Here's the thing. Most of these bands, even if I flagged them as "nope", the musical part is usually good... it's the singing I'm not a big fan of.
But, overall, great stuff man ! There are a lot of good suggestions here
