Overall Satisfaction with SharePoint Designer
We utilize SharePoint Designer across our own organization. We also install it for our clients and use it for them as well. SharePoint Designer is currently a necessary evil for our SharePoint clients. The biggest business problem that it addresses is the need to create custom workflows for SharePoint which is mostly what we use it for.
- Workflow Development - SharePoint Designer is currently the go-to tool for creating custom workflows in SharePoint.
- Allows you to easily upload resource files.
- It crashes...a lot! Be prepared to be making back-ups and hitting save frequently if you don't wan to loose your work.
- The HTML Editor is sub-par. I use other tools such as Visual Studio or Sublime for HTML Editing and just copy the code to Designer.
- It's being phased out. Microsoft announced that no new versions of SharePoint Designer will be released.
- SharePoint Designer is free so it's pretty easy to get a return on investment.
- It allows you to create fairly complex workflow fast to automate your business processes.
- Flow, Visual Studio and Nintex Workflow
There really isn't a holistic, complete SharePoint Designer replacement currently. You can utilize several different tools and piece together the functionality of Designer. No one really "selects" SharePoint Designer, it is just a necessary evil. For O365 subscribers, Flow is worth investigating for replacing the workflow function of SharePoint Designer, however, it doesn't have all of the features that Designer does. If you need a large scale workflow solution, there are third party tools such as Nintex. As far as the HTML editing capabilities, there are several tools such as Visual Studio, Sublime, TextMate, etc.
