On the other hand our school was moving to Moodle from something else (I think it was called Blackboard? Maybe https://en.wikipedia.org/wiki/Blackboard_Learn?) and it was an absolute pleasure compared to the alternative (which a few courses still used). There were definitely a few clunky parts (like the form) but overall it worked, was reasonably fast and wasn't awful. This was a student PoV though, really I just needed it to render some rich-text content provided by the prof and the occasional assignment submission or quiz. IDK if setting these things up was particularly painful.

This was about 8 years ago now, IDK if it got worse or better since then.

I'm surprised there's really much alternative. My schools either used Moodle or Blackboard and Blackboard was absolutely awful since it was a product of just acquiring and suing companies out of competition.

Hope your school wasn't moving to Blackboard ...
