They are both are obviously very talented at identifying players, coaching and motivating them and integrating them into a system that challenges for every honour.
Who wouldn’t want to play for either coach.

For me what is giving Klopp the edge is that he has developed both Dortmund and Liverpool from also rans into winners.
Pep has inherited all his clubs who were at or near the top, consolidated them and made them better.
Of course unlimited funds will help, but he still needs the talent to make it work - just missing that next champions league win.

This is kind of like the Messi/Ronaldo debate - value of medals aside its peoples opinion and perspective that keeps it interesting right now.
