Even i find DT kinda boring now. Definitely not the worst but boring.
I did like them to begin with(still do like some of their stuff), but they haven't progressed much at all. It just gets bland and boring after sometime. I mean, they have one of the best guitarist, drummer & bassist. They can pretty much play anything if they wanted to...It's just sad to see very less progression over the years. They have been around for quite a while now...cmon, they can atleast change it up a bit.
Anyways, I'd consider Pain of Salvation to be the best.
Truly progressive. I liked everything from 'Entropia' to 'Be'.
Quite a few fans hated 'Be' but i would consider it one of their best. The live DVD version is especially awesome. And oh, there's no point in listening to them without checking out their lyrics. I know few ppl who listen to DT/Symphony-X are in it just for the instrumental masturbation.(I try to make it a point to check out the lyrics also, even on first listen)
