Whew that's a tough one! It's tough to say because there was a time where prog rock bands ruled the rock world - for instance, when Yes released the monolothic "Tales from Topographic Oceans", a double album conatining four ~20-minute songs, not only did it sell well, it debuted at #1 on the US Billboard charts! That's the opposite of underrated, really. If we're looking at today's prog rock bands, well, it depends. There's bands like Dream Theater that are essentially prog-metal and have a sizable following from fans of both genres. But then there's bands like the Flower Kings and the Dixie Dregs that have a loyal fanbase, but do not get a lot of recognition. Which IMO is a shame because there's a lot of great music out there that's getting passed over.
