I haven't used django-ninja but to me it looks like the API is a bit nicer or more 'modern' looking (i.e. declarative via type annotations) and it's faster, both due to being based on Pydantic

DRF is old and API looks more like Django forms or class-based views, more of an OOP hierarchy going on, and DRF serializers are slow

Old is a harsh word, maybe mature would be a better fit, not everything new and shiny is gold, and yet not everything old sucks.

Not arguing here about types and Pydantic being faster than the built in ModelSerializers. However, for serializer speed improvements and performance in DRF I would advise dropping ModelSerializers and either going for Serializers or plain dict. Haki Benita has a beautiful article on that [0]. I was able to accomplish sub 200 response times on a fairly large response from tables that had tens of millions of records.

I think you have no objective reason other than your styling and rather personal preference for function based views?
