Depends if you are playing in a limited or unlimited format.
For a Black/white on format. Skyarrow bridge can be handy if you use a lot of Pokemon with 2 or less retreat cost, as it can help you get Pokemon out of the active spot.
Tropical Beach is a great stadium if you're trying to get Stage 2s on the 2nd turn with the help of Rare Candy !
Thats all I can think of for now. If you're using unlimited format, there may be other stadiums to consider but I am only used to playing the tournament legal B/W on format.
