I switched from Fusion to FreeCAD when I bid Windows goodbye (this video inspired me https://www.youtube.com/watch?v=VEfNRST_3x8). Fusion does a LOT of stuff for you that FreeCAD doesn't - i.e. extrude a pad from two intersecting shapes in a sketch. While this is annoying at first I feel it forces me to design smarter. I've had a few crashes and the constraint solver sometimes seems to behave weird and takes a ctrl+z and a second attempt at the same action to properly add a constraint but overall my experience has been pretty positive.
