Who is the better trainer: Floyd Sr. or Roger Mayweather?

[Nameless]

I don't know which one is best but as far as I've seen it, Floyd S.R is very erratic and unreliable and Roger doesn,t seem to have a list sheet for such behaviors, if I was a professional boxer, the first thing I would want in my corner is stability and reliability, if my only option is one or the other iof the Mayweather, I go with Roger for the reliability aspect big time.

I know who's more entertaining. Just look at that mug.
