Well, that depends on the variable. Options (i.e., those defined 
with defcustom) are really meant for user customisation: meant to 
be set explicitly by the user, and meant to be forgotten once set. 
If you want to save a variable that changes regularly and that the 
user doesn't set explicitly, then a user option is a bad fit. IMHO 
the best way to deal with that is indeed to use a separate file 
and to provide a user option to set the file path & name. That 
way, users can decide for themselves if they want to keep the file 
under version control, sync it across machines, or not.
