What a terrible list
DEP is technical Hardcore. Not metal. Not even metalcore. Besides Under the Running Board and Calculating Infinity were really great albums. All their stuff since then has been god-awful though.
JFAC went from run-of-the-mill deathcore to run-of-the-mill deathmetal. They are neither the best or worst examples of either genre. Just mediocre.
The worst you could say about Municipal Waste is that they are un-imaginative and un-original, but they aren't the "worst" of anything by any means.
The Haunteds first two seemed alright from what I remember, but that's all I know from them.
