Who is your favourite fighter of all time

First topic message reminder :

It's a topic me and a few of my mates were discussing the other night. It's not who you think is the best but who was your favourite. I went for floyd Mayweather in the end I'm only 25 and found it hard to pick someone I never watched live, you don't get the excitement of the fight.
Mayweather was the best I've ever watched so good defencively and his hands were so quick. People may say he picked and chose his fighters but he has outclassed top 10 contenders for years and has never been pushed to his limit.

Not my favourite of all time, but I'll give Vernon Forrest a shout because he never gets mentioned. Nice guy, interesting to listen to and a very good boxer.
