Nintex Pros and Cons

It is a good solution, easy to use and efficient when it comes to building quick business processes.

I would recommend Nintex and it's solution for businesses that require easy and immediate solutions. Nintex provides a good combination of ease of use and good capabilities, which doesn't require specialist coding skills to implement.

Nintex is less appropriate in scenarios where high customization is required. The form is limited in terms of how much you can customize and how powerful the logic/rules can be set up. In these circumstance Power Apps might be a more appropriate solution.

Also, as Nintex is a third party app. Major changes from Microsoft can cause problems. As Nintex communicated, the Office 365 Nintex workflows would all be made redundant due to changes from Microsoft in how they process SharePoint workflows.
