Unless there's more you didn't explain, you weren't burned by Django -- at most you were lightly singed by your own expectations. Everything you've described is more a matter of "I liked this one more than that one" -- things that are so minor or inconsequential to the actual hard work in building a SaaS app so as to be rounding errors. On the other hand, you haven't described a single area where feature parity is lacking, so it comes down to a matter of opinion and taste.
