No, they are not.

Foursquare has well-curated data that's easy for users to edit and update. Duplicates are removed quickly, closed or moved places are updated almost instantly. It's an excellent gamified system for building accurate location data.

Facebook, on the other hand, allows you to attach a freeform place to anything (photo, event, review, whatever). These freeform places are not managed well. In a cursory search for a common park in my city, there were 12 duplicates and 8-10 irrelevant only slightly related places returned. The correct place was at the top, but a duplicate was in the top 10.

It could be an Apple Maps situation. Bad now, but likely will get better as people use it more.
