Best Practices for Dealing with `Effect.Effect<R, E, void>`: `flatMap` or `Tap`?

What is considered best practise when dealing with an

Effect.Effect<R, E, void>

Effect.Effect<R, E, void>

where the operation returns a

void

void

. Do you

flatMap

flatMap

or do you

Tap

Tap

?

E.g.

Effect.tap((cookie) => Ref.update(cookies, HashMap.set(name, cookie)))

Effect.tap((cookie) => Ref.update(cookies, HashMap.set(name, cookie)))

Effect.flatMap((cookie) => Ref.update(cookies, HashMap.set(name, cookie)))

Effect.flatMap((cookie) => Ref.update(cookies, HashMap.set(name, cookie)))

Or does it not matter?
