Well, you could start the manga immediately after the anime. It'll give you more details and potentially expand on the storylines you loved in the anime. However, if you need a break to digest what you saw, waiting a bit won't hurt either.
It depends on your personal preference. If you can't wait to know more about the story, start the manga right away.
I'd suggest starting the manga shortly after finishing the anime. That way, you can continue the adventure and get even deeper into the world and characters. But it's up to you if you want to take a break first.
