Hard to pick one, but I went with Melodic Death. Seems the bands that have touched me the most since I was an early teened metal worshipper have been more on this side of the spectrum. It's just hard to pinpoint which aspect is more favorable, be it true or extreme metal

.
I just love how limitless the metal world is to sub genres. You have death metal stars writing power metal albums, black metal demons performing like angels in experimental/technical/avante-garde prog, and of course the power of any vocalist that can induce a satan-esque roar in the midst of a heavenly powerful octave range. It's hard not to exclusively worship METAL when the style has so much to offer. I wonder who voted for "nu metal?" lol.
