More Formidable Fourteen? Federer vs Tiger

I say both accomplishments have been equally hard. On one hand, tennis is a one-on-one competition with more stress on athleticism, where you actually sweat and expend energy. OTOH, golf is man against nature and nature is tough.

i feel tennis is physically more demanding when compared to golf.Especially when are playing against someone as mobile as Rafael Nadal who will go all out just to keep the rally going and in the process pull off stunning returns,you need to have just that extra bit to win. Even though Tiger Woods is one of the greatest golfer,I think Federer has done just enough to pip Tiger Woods.

with recent developments in woods life, federer decency should make him the front leader in the race i guess !

Roger Federer is the best...Tennis is more tough game compare to golf..You need to have both techniques of the game as well as you will have to be a good athlete to be the best tennis player .Tennis is a interesting game too!!

I do believe that tennis is one of the most physical game sport in the world... & Your level of mentality & intelligence must be higher than your strength to achieve greatness... & This is where Roger Federer stood best.... He's got grace, brain & strength... Though, it's really hard to dominate that long in tennis unlike in golf where you can still play professionally @ 60... So I give more credits to Tennis great achievements than golf's pure mind supremacy...Tiger would still win more Majors in the Future while Roger might win 2 or more if his health & body would allow.
