Purpose and Comparison of `Effect.fnUntraced` and `Effect.gen` for Parametrized Effects

What's the purpose of

Effect.fnUntraced

Effect.fnUntraced

? How is it different from

(...args) => Effect.gen(...)

(...args) => Effect.gen(...)

apart from having a built in pipe? Should I prefer one over the other for parametrized effects?
