I would say they're a lot better than Rush, because (a) they purged a lot of the more overt pop sensibilities from Rush, (b) the singer is not Geddy Lee (the guy plays a mean bass, but his voice is awful), and (c) the synthesizers are far, far better.
Also, a prog band needs a lot MORE songwriting skill than a regular heavy metal band, because the material is more complex, there are no more hard and fast rules, and you often have to tie a lot of very disparate elements together. These guys even managed to beat a killer song, "The Mirror", out of groove metal, the hideous bastard stepchild of metal genres.
Also, if you get lost during the solos, it's your fault, not theirs. Follow the drum and bass grooves if you get confused.
If you think this is random shit, I wonder what you'd make of fusion jazz. Some of it is so complicated and dense that you have to pay undivided attention to it constantly or you get lost. I am not kidding.
