Which playoff run was Duncan’s best ?

For My True NBA Fans:

2003 is considered one of the best playoff runs ever and one of the finals performances ever. But as an NBA fan, of course I looked into it watched film and studied these stats. And can't deny the excellence shown from Timmy D, but I want to raise a question was it really his best ??? Because Tim Duncan in 99 has a case that can be made. Think about Jr yes Duncan in 03 got more boards in 03 and even more blocks. But then you look at 99 and then you look and see who he faced and who he has beside him (Drob) who could in fact lower his board totals a bit and blocks, and in the finals imo the Knicks had a better team than that 2003 Nets team.

So with all that being said, which year for Duncan you taking as his best 99 or 03?
