The pain point of SharePoint Designer is sometimes it gives you issues that can be resolved mostly by clearing the cache, but Microsoft should still work on it and make the product more stable.
Another issue related to SharePoint Designer is that with the newer SharePoint versions, Microsoft hasn't released a newer version of SharePoint Designer. Instead, Microsoft is recommending that you use the same old SharePoint Designer 2013. If Microsoft updates SharePoint Designer, the product will be more beneficial.
