As for the classics my favourite is Paul Keres. Not only in terms of chess but generally as a person. As for today, I like Alexander Grishchuk. Very talented and has a sharp wit.
Favourite person in the chess world?

I like Yasser
Excellent and lovable commentator
Yeah, the most calming voice ever with funny and interesting stories.
Also of you like chess history, checkout interviews with Frederic Friedel.

I like Alexander Gelman.He is not a world champion or even a grandmaster.But all the other commentators are no match for him.
By no short measure the finest individual ever to grace the tournament room is Vishy Anand. I saw him playing in London and during rounds he mixed with all levels of players from beginners to masters. He is truly a great person who could easily deal with fame, unlike many other professionals in all sorts of sports who become 'divas' when they haven't even achieved a tenth of Vishy' success.

He is an asset to the Chess world and I love watching and listening to him commentate.

Fore me it's Vassily Ivanchuk, he is one of those players that for me has the most unique playstyle i have seen in chess.
Magnus Carlsen, Then maybe Eric Hansen or even Samay Raina( He is very funny)
