TYG02 and YUDENT002 often give better burns than Verbatim 8X media these days, but the new 16X TY discs are not better in this area than MCC 16X Verbatim. The problem with these (MCC004 and MCC03RG20) is that there are more and more reports of media quality variation. - TY is far more consistent.
Now the overlooked problem, if one's concern is longevity, is that TY DVDR media is far more fragile than MCC DVDR media, easier to scratch, easier to break, to damage etc... so it's not a clear cut. For people who take great care of their discs, the overall picture is different than for people who are a little rougher in their handling.
There are plenty of other choices BTW. Right now I think the best discs on the market are neither TY nor MCC, but the TDK-branded MBIPG101 R04. Good price, great burns, sturdy discs, and very stable according to accelerated aging tests (but I don't know if it's possible to find them in the US).
Dakhaas said that the Philips-branded version of these MBI discs is even better, I have no personal experience with them, but I tend to trust the man.
My two cents.
