federer forehand is the best i have ever seen. no doubt in my mind. his forehand nowadays is less of a weapon but still top 2.
about footwork... man, nadal is faster, i think, but also puts more effort into the running business. most of the times federer quits. different aproach. nadal thinks short term, federer thinks long term. this makes nadal footwork/speed more obvious to the observer.
but federer has, BY FAR, the best footwork, meaning that he is more efficient, more effortless and overall better at playing a shot from a good standing point. his balance is uncanny and the guy can adjust better than anyone else to anything. look at novak's movement on grass. look at nadal's movement on hardcourt (doing what he does on clay...). nadal and novak are so often unbalanced, almost falling (and sometimes actually falling)
, playing from some strange and body-wrecking position. kudos for them for the effort, but i just dont see it as good movement, only athleticism.
plus, its hard to put a guy like nadal next to a guy like federer, because federer moves side to side but also back to front and front to back. because he is an all courter, his movemente is also a reflection of this. nadal is basicly a side to side kind of mover.
said this, i think the 2 of them are, from this era, the best movers and have also the best forehands, what i think tells a lot.
