It's great for introducing people to HTTP, I always refer inexperienced new-hires to use it since it has proven to very effective at getting them up to speed. In many ways you could say Postman offers a GUI to the protocol itself, making it something you can visually explore. I see stuff like curl as a more advanced tool for people who already know what they are doing. In fact Postman even offers a curl "export" option that lets you see how to do whatever you have done in Postman, using curl instead. So arguably, it's also a good introduction to curl as well.
