You would think, but then this is the same forum that incorrectly tosses around the term "pusher", "vulture", and even "talent". Are you suggesting that there's not such a thing as "current best"?
And no, it's not. Turn your bias off and try again.
No I am not, and the question being at his peak appear to be pretty straightforward.
As for who's the best at his peak, the only answer that is a credible one is obviously Federer, anyone who is not a delusional No2e fangirl or worse, a Rafatard, will tell you that.
Who is better now? Well look at the ranking. Is Federer not #1? Sure looks like he is. And when you look at their respective records this year (61-8; 6 titles for Federer / 60-11; 3 titles for No2e) it is difficult to pick No2e over Federer.
Mind you, some idiotic fangirls will claim that Nole 2011 was better than Federer 2006 even if the W-L ratio and titles won clearly show Federer had a better year, so nothing would surprise me. Like you said, this is MTF where ridiculous statements are made on a regular basis...
