Many developers have one common question – which of the framework is better? You might have got a fair idea by now of how each framework works and what are the best ways to use each of them. That said, there are many high traffic websites built on Flask as well, which perform well and are comparable with those built on Django. Quite a few basic concepts are the same in both Django and Flask, but Django is complicated and vast and requires a deep learning curve, so if one wants to get the'feel' of a web framework, start with Flask and then move on to Django for more sophisticated applications. Or you can master one and then switch when your job needs you to, rather than having to learn everything at once.
