Which of these would you buy?

What??? People have said try Wolverine. I've said ok, gone to YT and tried a song or two then decided that one is not for me. I didn't say I was going to blind buy something just cause loads of people said do it. Jesus.

All anyone can ask is that you check it out. If it's not your thing then that's cool. For me personally I think the Wolverine is better than anything on your list, but different strokes for different folks .. ya know.

These would be my top choices:

Candlemass - King of the Grey Islands
Threshold - Subsurface
Vanden Plas - Beyond Daylight

I will have to check out Wolverine to see what all the debate is about.
These two for sure:
Candlemass - King of the Grey Islands
Therion - Sirius B

And one of these, but undecided which:
To-Mera - Delusions
Wolverine - Still
Dream Theater - Train of Thought
I don't think you will ever learn that content and context are both equally important when attempting to persuade or influence other's opinions. Otherwise, it is just a statement about your own taste.
First off, good to see so much love for Candlemass - King of the Grey Islands. As for my other three they would probably be Dream Theater - Train of Thought, Therion - Sirius B, Scorpions - Humanity Hour and Primal Fear - Seven Seals.
