Donaire has to be respected for agreeing to full random drug testing the year round, also for fighting four times this year. Others have been mentioned such as Klitchkos, Martinez Marquez, Ward, Froch, etc. They work very hard, are relatively humble and seem like nice guys. Id probably say Pacquaio in the way he conducted himself in the Marquez fight, the build up and afterwards, he seems a classy guy and is a warrior.
for those that say andre ward. when the cameras are not on, what you see is what you get. that's the real him that you see on tv. i use to train at kings gym in oakland and he'd train there as well. share the same dirty stinky locker room with the boxing misfits like me who was there to just get some excersise, greets people at the gym before they even greet him, show the kids some boxing fundamentals but clearly shows that he's annoyed when he hears kids using foul language or talking down to one another, clean up after himself after using the equipment like the weights, wipe his sweat puddle on the floor, help gym members who were just nobodies like me with family stuff like moving houses and stuff. he was so easy to talk to that i didn't even get an autograph from him because he's so accesible and makes you feel like he's no special than anyone else. maybe that was his secret weopon to avoid autograph seekers is to make you feel he's no different than he is. and now i don't train there i wish i did get his autograph.
