For a setup problem in a reg-to-reg path, the best approach is to insert the buffer near the launching flop.

Reason: Inserting the buffer near the launching flop delays the clock signal to the launching flip-flop, effectively increasing the available time for the signal to propagate and meet the setup requirement at the capture flip-flop. This helps in resolving the setup timing issue.
Placing the buffer near the capture flop would increase the clock delay at the capture end, worsening the setup problem.
