Mayweather and Hopkins

Recently I have been reading a lot of posts taking about moving up in weight classes, and the significance it has on a fighter's ATG standing. In particular, a lot of posters use the fact that Mayweather has held titles in multiple weight classes as justification for putting him higher on their ATG lists than guys like Roy Jones, B-Hop, and James Toney. However, I think when we look at how a fighter transitions between weight classes it is important to look at who the fight, and what titles they accumulate. I propose that Bernard Hopkins deserves more credit for his multi-division accomplishments than does Floyd Mayweather. Hopkins knows how to do it right, he moves into a new division and immediately goes after 'the man' whether it be Tito Trinidad, Antonio Tarver, or Tomasz Adamek (admittedly this fight isn't happening but it was discussed). Mayweather on the other hand has seemed to rely on his unbeaten record and an accumulation of lesser titles to make up for the fact that he has not established himself as 'the man' in any one division in at least 4 years. At the end of the day they are both great fighters, but I have to give the nod to B-Hop on my atg list. So, who do you guys think has implemented the better strategy when it comes to transitioning between weight classes?
