I found FreeCAD more difficult to learn than other 3D CAD programs, but the 1.0 release that came out about a year ago has improved things a lot. It also looks like 1.1 (being stabilized for release right now) is going to add a lot of nice features.
It seems like the product is having a bit of a renaissance. I'm not sure how much of that is coasting on the work that Ondsel (now defunct) did over the past few years, and how much is sustainable momentum. Hopefully more the latter.
The boundary representation kernel that FreeCAD uses (OpenCASCADE) has some limitations, and it's unlikely that those will be resolved. They make for a bumpy ride sometimes.
I think FreeCAD is almost becoming usable enough that it's reasonable to try to learn it if you want to use free software, or want to create models that you can use commercially.
If you don't care about commercial use, or you are willing to pay, I think OnShape is more powerful and significantly easier to learn and use. It uses the Parasolid kernel, which is more robust than OpenCASCADE. It's free for non-commercial use with the caveat that your models have to be publicly visible. https://www.onshape.com/en/products/free

If you want to learn FreeCAD, here's what I recommend doing:
- Install OpenTheme and OpenPreferences. https://old.reddit.com/r/FreeCAD/comments/1j82svt/i_really_w.... These fix a lot of the sub-optimal defaults that FreeCAD ships with.
- Increase the marker, font, and line sizes in sketcher and display preferences.
- Watch Mango Jelly and Joko Engineering videos on YouTube to learn how to do things. Focus on videos about FreeCAD 1.0.
Good luck!
