I know I've said this before, but: Easiest. Round. Ever.
I find Geoff Tate to be annoying. I have nothing against Queensryche's music, though, and this is easily one of the best songs I've heard from them. I actually think I voted for it in a previous round (it was probably up against a 15-minute track of people banging pots in a forest).
I have no ill will towards Travel in Stygian, as I find it to be one of Iced Earth's better tracks from their earlier years. I think the version from Alive in Athens with Matt Barlow singing rips the studio version to shreds.
Disclaimer: My opinion of Iced Earth's music has not changed and will not change based on Jon Schaffer's poor decisions.
However, Blackwater Park is my favorite Opeth song. Ghost of Perdition is in my top five. This is no contest.
One of the best descriptions of Opeth I've ever heard! Kudos.
Åkerfeldt’s growls are some of the most grating and annoying extreme vocals I’ve ever heard
I am not a fan of most death metal bands because I find their extreme vocals to be far weaker than Akerfeldt's. And I'll say that while it took me years to get into Opeth because of their vocals, once I did there was no going back. Since dropping the growls they have become a shadow of their former selves, with Pale Communion being the only post-Watershed album that gets any regular plays from me.
You may like Damnation, which was released during their growliest years but contains no harsh vocals. It's a brief listen, too, at only 42 minutes. Save it for an autumn or winter day. Additionally, if you like retro '70s hippie prog, check out Pale Communion, In Cauda Venenum, Sorceress, and Heritage (in that order). Just be prepared to crank your treble and lower the bass (and I say this as a bassist).
