Hi,
it all depends really...and the best place to look for the info is probably the manufacturer datasheet.
For example, we are using 2 legged and 3 legged crystal here and the difference between them is whether they have built-in capacitors.
I am convinced that a 4 pin crystal has 1 or 2 of its pin not connected anywhere....
to be checked...

Can anyone tell me the difference between 2pin crystal and 4pin crystal packages and cct symbols and their behaviour
