Heavy Metal Haven

Kai Hansen - The Godfather of Power Metal. He's been in four bands now, although Unisonic's status as power metal is a bit iffy if you ask me. Which is best?

Helloween (1983 - 1988)
Gamma Ray (1989 -)
Iron Savior (1996 - 2001)
Unisonic (2011 -)

This is tough. But Helloween.

This may come as a surprise but I'm going to actually say Iron Savior. I think all four are good (though I don't Unisonic is ever going to be near as classic as the others) and that Helloween and Gamma Ray are both legendary acts, but Iron Savior has, IMO, had the most consistent career so far, whereas both Helloween and Gamma Ray have released some lesser albums.

^ Haha, that would've been my argument for Gamma Ray...

So what Iron Savior album don't you like as much?

I haven't heard every album from either Gamma Ray or Iron Savior. I'll say Helloween for now. Might change.

Gamma Ray for me, at least right now. Even though they have some weaker albums, their best releases far outrank anything I've heard by the other bands so far. Then again I've only heard two Iron Savior albums (one of which didn't feature Kai) and haven't heard Unisonic's album in it's entirety. I have heard all his Helloween stuff, but Walls of Jericho is the only album that I still listen to from time to time.

Megatropolis would be such an album for me; all previous ones were far more exciting imo, but each to his own of course Gamma Ray's career also lasts about ten years longer yet and there's no album I'd rate below 7/10

After some thought, I have to go for Gamma Ray.

I can say the say about Gamma Ray, but Iron Savior it's 8/10, which is what I'd give Megatropolis. It's a low end 8/10 to be fair, but I'd rate most of Iron Savior's works as 9/10, although The Landing is the only 10/10.
