It's not the same -- Relay Modern and Apollo Data are both a bit half-baked still in terms of client-side state caching. GraphQL mutations are painful to code right now. I say all this as a long programmer on my side SaaS -- with a team, things aren't quite so bleak. I really want to go GraphQL but it's just too complex still. Redux is much simpler to reason about. It is a simple state store. The client side state caches are just not there yet from what I can tell. There is too much magic and not enough time on the market to trust my business with them.

I'd love to hear contrary experience.
