Org mode has so many more functions than workflowy. You also don't need any of the keyboard shortcuts -- they simply Ardmore efficient ways to edit text, but they are just editing text. Orgmode is also plane text and extremely easy to replicate, even with Dropbox &c.

Workflowy has the opposite problem of orgmode. Workflowy owns your data and unless you frequently sync it with your hard drive then you risk losing all of your notes.

However, the best tool is the one that fits your needs and that you're familiar with. That said, would I encourage you to Wade into the orgmode pool? Most certainly!
