I'm never sure what their best album is. They've never had an outright classic. Night of the Stormrider has kinda lame vocals, Burnt Offerings has an amazing first half but a bit too much filler, The Dark Saga has some hella fun songs but is too dumbed down, and Something Wicked this Way Comes is probably their most consistent but is too bright and shiny and business-as-usual. I guess I could go with Burnt Offerings as it has the best version of their sound.It'll probably sound like the last however many albums anyway. No thanks. Burnt Offerings will always be the best thing that band did.
Their Highwayman cover is tits..but thats where I draw the line.They've never really released anything that has impressed me, mostly for the reasons @The Batlord alluded to. They seem like they can never get a whole album right, there's always some glaring, unavoidable problem.
