Both Wrike and Smartsheet are very good project management tools, but it really depends on your needs and which areas you excel at.
Wrike is best if you need a super flexible tool with intense task tracking and workflow management. Its features are designed for very specific visibility and control, which makes it great for productive teams that need to manage complex projects with streamlined collaboration of either in-office or remote workers.
On the other hand, Smartsheet is perfect for users who want to have an interface that is less complex and more of a spreadsheet type. It is great for real-time planning, with auto features and reporting. It offers an intuitive approach to industries in such a way that it becomes easier to get through and deal with different types of simplicity in carrying out projects.
I suggest Wrike in case greater flexibility in managing tasks and workflows is needed. If you want a very user-friendly spreadsheet-based platform applicable to all industries, then go for Smartsheet.
