I would bet on development speed. Using SQL and No-SQL software brings a lot of engineering, you have to decide where to host, how to host, who is going to take care of that. This translates into costs. After that there's a new bunch of problems, it's required to engineers to know the platform and create the software for that. After that there's maintenance, etc... all things services like Parse and Firebase removed, with the trade-off of less flexibility, but as I said before, this can be a problem later in the development stage...
