I know Unexpect, and yes, they're diverse, and unique, and interesting. But I honestly can't stand too much of them. Yes, they get crazy. Very crazy. And sometimes, so crazy that it's practically unlistenable. And frankly, I'm not a fan of Death Metal Screaming. I think it's damaging their music.
Personally, I think there is such thing as Too Extreme. Which is why I don't get people who say like, "Oh yeah, I loved Iron Maiden, they were my favorite Metal Band. But then I needed something heavier, so I started listening to Megadeth. But then I needed something heavier, so now my new favorite band is Cannibal Corpse." And in the case of Unexpect, yes they have some very pleasant things about their music, their orchestral, melodic parts are awesome, but they almost get canceled out by the crazy, chaotic Death Metal parts.

Bolded bands are ones that I think are shining examples of how a band can have a repertoire of many different sides of the stylistic spectrum, and yet do it all in ways I have never heard before, and remain consistently themselves while not ostracising too many fans in the process.
Lady Gaga? You're seriously gonna tell me that Lady Gaga has as much range and variety as DT? Gimme a break. New and unique? Sure. But while she has SOME variety, it's not that much.
I don't hear anything unique or innovative about Tool, or Opeth, or Thrice. Maybe they're diverse, but I wouldn't say they're anymore unique or innovative than DT. DT still has a sound that's more unique than those bands. What I mean is, I heard plenty of bands that have a similar sound to Tool. Maybe I'm wrong, maybe those bands were imitating Tool, and Tool was the first to do that sound. But I still don't think it's all that interesting. Opeth I guess to an extent has something unique about it, but I still wouldn't put it as more diverse or interesting than Dream Theater.
Now, it's another thing if you dig those sounds more than Dream Theater, there's nothing wrong with that. But that can't be debated, because it's all a matter of opinion. And sure, those bands are good in their own right. It's not like I never heard them before. They just never caught my attention enough to say, "This sounds great. I definitely want to hear more from this band." Which was even something I said about Disturbed, even if they're not all that diverse at all.
