Comparison

--- redux-observable redux-saga
Style Nested pipelines, need to reason how many times you need to "unpack" an Observable Synchronous-looking code; can be deceiving
Learning curve Several operators, though simple API. The reasoning is not straight-forward Small set of effects, API almost inexistent besides the operators themselves
Async primitives Introduces the Observable primitive, which unifies all async APIs. Perfect ergonomy for streamings. Uses promises and event channels (API similar to Observable). There's no built-in solution for streamings, but it's not difficult to write one using the effects.
Extensability Easy to create new operators and new adapters for custom async operations that are not yet adapted Easy to use existing effects with custom promises, but it's not possible to create new effects
Browser support ReactiveX/rxjs#998 Couldn't find; probably the same as the generator transpiler https://facebook.github.io/regenerator/
Documentation Kinda confusing, there's a general Rx documentation and a specific for RxJS. The easiest way to understand the operators is through the RxJS Marbles website. Extensive and clear documentation with several practical examples.
Community Smaller redux-observable community, but giant Rx community. The standard solution for advanced async patterns for the redux community.
Sponsors Microsoft and Google (standard dependency in Angular). No big sponsors (the biggest is Rollbar).
Usefulness outside of the scope of the application Uses Rx with principles of functional programming Uses go-like CSP model
