Both ripe Pu'er tea and black tea are fermented teas. The teas are mild in nature and both have stomach-nourishing effects.

If you want to drink Pu'er tea, it must be cooked. Pu'er tea can nourish the stomach. If it is black tea, black tea is more suitable for people with cold stomach and weak body. Some friends may get angry easily and their gastrointestinal function is not very good. Well, if this kind of person drinks black tea blindly, it may cause dry stool.
