1) Jennifer Aniston - every time I re-watch an episode, I'm amazed at the sheer level of charisma she has in every single scene. 2) Matthew Perry 3) David Schwimmer 4) Courteney Cox 5) Lisa Kudrow 6) Matt LeBlanc
You couldn't really ask for a much better sitcom main cast, honestly.
1. Kudrow - Blows the other 5 out of the water. She operates on an entire different level. 2. Schwimmer - Great body language and comedic timing. Ross sucks though. The more I rewatch the show the more I hate him. 3. Aniston - Awful in earlier seasons, but improved significantly as the series progressed. 4. Perry - I tend to believe that people only like Matthew Perry's performance because people love Chandler, the acting performance itself is honestly nothing special. 5. Cox - The opposite of Aniston. Good at the beginning, but went downhill as the series went on, and her highs weren't as high as Aniston's. 6. LeBlanc - Hurt by the subpar writing on Joey. By far the thinnest character of the 6, consequently LeBlanc didn't have much to offer.
