I will say that depending on the match up and the fighter I tend to favor the old school fighter over todays fighters.

Tiger, Monzon beat any of todays Middleweights.
Griffith, Armstrong & Napoles beat any of todays Welterweights.

For me it's because Griffith fought the best available sure he lost some, but he also won some. He fought 2, 3 times a month. He challenged and beat HoF'ers.

Todays fighters with the exception of a handful just don't do that.
