Being from Realm, I might not be the right one to give you a balanced view, but I can at least try a bit:
One huge difference is that Parse is no longer developed by a company after Facebook abandoned it. It's been open sourced and its future is up to the community.
Another is very related to this article. Realm resolves all your conflicts automatically, the developer doesn't have to do that. That's even done more fine grained at the property level.
Realms focus on being an offline first database means that your data is always available locally.
Then there are subjective differences. Until the launch of the Realm Mobile Platform, Realm has not had a solution for syncing to a backend. We have a lot of users who have chosen to use Realm locally and Parse as the backend. I guess that's a testament to the local database features from Realm. But with the new syncing solution, that's no longer needed, and all the networking code can be forgotten.
I'm sure others can come up with pros for Parse, but if you are not already invested in Parse, I think most would recommend looking elsewhere due to the first point.
