Looking for good metal bands?

I've been looking really hard for so long and I've still only found a handful. I'm a big metal fan but I'm very picky. There's two bands that I really like and they're Slipknot and Mushroomhead. Now I know you might be thinking I only like them because they wear masks but no, the masks are cool but I only care for the music. Slipknot of course has set the bar for truly beautiful brutal music with their first two albums, it's too bad that they don't make enough of it. Mushroomhead has an intriguing sound. I dont know how they do it but so far, they have not made an album that disappoints me. I do like some other bands like Rammstein and Static-X but I only have a few of their songs.

I personally prefer bands with good vocals, that's usually what sways me. I like bands that have good lyrics. But just jot down your favorite bands(in order of your most to least favorite) and I might check out the ones I haven't already. Please and thank you :)
