Gym Buddies, Yay or Nay?

This probably isn't the first time this has come up, but what do you guys think? Do you like having a buddy to go to the gym with or do you prefer gyming solo?

No one to hold you back or slow down your workout, you're 100% focused and ready to go. This is what I call true Beast Mode. Like this (ok not really, but come on it's so cute, I had to post it):
