I voted no, but it's not really that simple for me.
I have a lot of respect for Octavarium, and I would say that in terms of objective artistic accomplishment - insofar as such things can be measured objectively, of course - it is surely among their best. That being said, I find that I don't like Razor's Edge quite as much as most people seem to, and while the first half of the song is nice in its own right, I don't often feel compelled to listen to it. I actually saved the middle section of this song - 12:15 through 19:50, to be exact - as a separate track, and I listen to that track more than the song as a whole. It's worth noting that this particular stretch contains some of my favorite musical passages ever, so there is certainly a lot to like in this song.
But when I take it as a whole and listen to it from start to finish, it's not among my favorites. It's still a great song, don't get me wrong, but there are certainly quite a few DT songs I enjoy much more.
