The starting prices for hobby instances [0] (i.e. development) are about half of what you would pay for AWS RDS [1]. If you choose to have high availability then prices are equal in this case. This is for Crunchy Bridge, which has a calculator on the website. Although, similar to Amazon RDS the prices increase dramatically as you get a decent machine to run your database and increase storage size. I'm using us-east-1 for the comparison.
Honestly, as always, I think these managed database services are way too expensive. If I really needed to choose one of them I would go with the AWS service, because you also have to factor in data egress costs in your cloud costs calculation which will vary a lot depending on your workload.
