I've got both trades, and the original one is very good. The paper stock is slightly less newsprinty than the single issues (the ink doesn't rub off like with the single issues), and comparing the first two issues, the first issue in the trade looks better than my individual copy (ink's laid on a little heavier, more solidly black).
So yeah, it's a good collection with a really nice wraparound cover. Plus it's got a short story at the end titled "Tales of the Teenage Mutant Ninja Turtles", which I don't think has been printed anywhere else. (It's not in Shell Shock, anyway.)
My only sort-of-gripe is the covers are printed very tiny* and in black and white. The full wraparound art is shown, at least. (*Instead of displaying the art sideways to fill up the page, they display it left-to-right, leaving a huge margin at the top—more than half of each cover page is blank.) The '07 Treasury trade doesn't display the covers at all, so...
