PI/PO vs. 3T Jitter Tests

Hi I have a small question

what is more importent PI/PO test results or 3T Jitter tests. As I’m trying to choose between Plextor 708A(which has better PI/PO test results) and NEC 2500A (which yelded way better 3T Jitter test result).

I’m aware of all other differences between those drives. However the biggest concern that I have is write quality.
