I've had a bad experience with Gin and when asking about alternatives in a local Go meetup I was given the advice to use https://github.com/go-chi/chi or gorilla/mux.
One thing to note is that Gin's Context is not the standard context.Context, which some find problematic. Most (vocal?) Gophers prefer sticking with the standard library and Gorilla.
context: working in large org building backend services that speak to other backend services via various crappy http / rest / soap APIs.
