when you say "nice" in french, are you supposed to use sympa or sympathique?

Question

How do you say

1."Tennis is as fun as volleyball?"

2. "The chair is not bigger than the refrigerator?

Answer 1

"sympa" is colloquial or used in popular speech
"sympathique" i s likable, attractive; sympathetic

If you truly want to say "nice" that would be: agréable, gentil, aimable except for the weather and then it's "beau."

2. La chaise n'est pas plus grande que le réfrigérateur.
