Well i have many favourites and u must take the different surfaces seperate:
So my favourite hard court is:
Gstaad or Melbourne Indoor club, because there u have the best connection. Outdoor courts like Harbour bridge suck a bit because of the connection.
Clay court:
Definitely
Antanananarivo.
Grass court:

i just played on
hamburg dingsbums. One time on Bogota South African... but i did not like it that much.
