Learn MoreI'm not familiar with FME, but I'm also not a huge spatial guy. I have built several workflows however using many of the spatial tools available in Alteryx.

In addition to the point above, I would also spend a bit of time in the Spatial Analytics Interactive Lessons, which will give you a solid idea of what you can expect in terms of functionality.
