Wasn't a huge fan so I didn't have one. Probably season 2 to be quite honest. Since there was really no triangle stuff there... than again I felt Peyton/Brooke friendship wasn't really that strong in season 2 because of everything she was going through and of course Brooke relationship with Felix and how alone Peyton was feeling. I didn't feel Brooke/Peyton friendship much in season 5 from what I watched. I just felt Brooke was a great friend (especially in those first 2 episodes) but I forgot much about anything else there. Probably season 6 & 7 were the best. Whichever season where they were EQUAL good friends would be my favorite. For me, I have certain scenes I love the best but probably not a whole season....
