Sanga was really good to the spinner and Murali, but I do feel Prassana is better. Saw bits of him keeping against India and he was so smooth and quick.I honestly think Prassana is a bit over-rated, and that's as someone who likes sri lanka. He was clearly the most specialised wicket keeper about, being quite a poor batsman (although he's sorted this out and is a very useful bat now) but I don't necessarily think he is that special.
He maybe is still best in the world but there's hardly any real competition, most keepers right now are nothing more than functional.
IMO he isn't even the best in the sri lankan team, but sangakkara is under too much pressure to deliver with the bat to take on two roles.
I agree with the sentiment that he's isn't very special, but he's probably the best gloveman going around today.
