It's hard to do apples to apples performance with postgres - it really does depend on the data model and how you interface with it, but the thing about performance for DDB is that it can be very consistent. Pricing also depends a lot on your access patterns and data structures.

For me though, it's not having to worry about DB uptime, performance, or version updates that keeps me reaching for DDB even for small hobbyist stuff. But I'm also comfortable architecting for it, probably more comfortable than I am for traditional dbs, so that's a huge part of it.
