A Show of Hands is a great album: it has more heft than the studio albums and as a collection of songs is much more listenable than the 4 studio albums from which it primarily gets its songs. But it’s not in the same league as the other 2.
ATWAS is great for a rawer performance with significant changes to sounds of the songs. But as a collection of songs in a semi-live setting, ESL is the best.
