I'd argue Iced Earth. Yeah, Gene Adam is a horrible singer, but if you can get passed him, the album is pretty great. Still, I'd recommend compiling the Days of Purgatory tracks. Even though I prefer To Curse the Sky over Nightmares, you can put the latter on there (since the former wasn't "re-recorded") to make it a complete album, and it fits right in. I'd take the unaltered debut over Dystopia.
