Oh yea I totally agree. Despite Iconoclast songs being pretty short I thought they still felt bloated.
It's interesting because the last Dream Theater album was also an exercise in conciseness and I had the exact same issue with how they ended songs. The Looking Glass, Behind the Veil, and Surrender to Reason had really awkward endings IMO. However while Dream Theater doing an album of shorter songs was totally out of left field, Underworld feels like a natural progression as far as song lengths/structure goes. Plus SX never really had many epics. It's always one or two per album at most.

Every song's a killer! I can't help myself but to feel it's their Train of Thought - their heaviest and most brutal work, yet one of their best (IMHO!), a bit simplified, but still complex enough to my tastes, with keyboards a bit in the background and everything revolving around the axe player. And catchy as f***. Sir Russell Allen is a serious candidate for my current favourite singer, this album really shows his abilities quite well (the title track, OMG). I can't even name any favourite, every song is.
Such was the step up from Iconoclast (which I like anyway, mind you). This album sounds to me much heavier than most death metal I currently possess. 
(#3 would be probably Nightwish).
