Seaborn is a high-level plotting library based on matplotlib. Let’s have a look at its advantages in comparison to matplotlib:

• simpler interface;
• a wide range of default styles and color palettes;
• works well with pandas DataFrame;
• a wide range of built-in statistical functions.

Here is an example of a plot created using seaborn with just one line of code:

Apparently, everything you can accomplish using seaborn can be also done with matplotlib, yet it may often take more time and effort.

However, matplotlib being a rather low-level library in comparison, offers more flexibility for your plots, so if you need to create a rather unique plot with a lot of customizations, matplotlib is still the best choice.
