The Jester Race. And Clayman for me but that's rather because of the fact that I'm used to it.
Jester's Race is so much better than Whoracle.
I used to not like The Final Frontier but lately I've come to think that it's their most underrated revival-era album. I think its major problem is that it starts with several incredibly bad songs so that once you get to the good stuff you're already in a negative disposition towards the album or you've zoned out entirely out of boredom. Which is a shame, because tracks 6-9 of that album is the strongest run of songs of their entire revival-era discography.
