147 just because 1a and 1b are legit ATGs and best of their generation. They have bought a lot of attention to boxing since ODLH's peak. Any other time, I would have said 140. 147 is more accomplished resume wise (Pac, PBF, Mosley and Cotto). But 140 has a deeper young talent pool (Alexander, Bradley, Khan, Maidana, etc) which is exciting for boxing when Pac and PBF leaves us.
The division what has had the best bouts over the last few years, including this year is 147lbs...but after Mayweather and Pacquiao, there isn't much left...in my opinion. 168lbs has had a good few years because of the Super 6...and promises more big bouts once the Super 6 has finished...maybe a few rivalries aswell. 140lbs has the potential to take off in the next year or 2...this is probably the division to watch over the next 2-3 years.
In no particular order 168 140 147 154 126 These divisions seem to have the most prestige fights IMO.:good
im goin to say 168, with the super six going on and all top fighters guaranteed to fight no ducking allowed....
