Right, but it's the difference between using a beat up old hand saw and hammer vs selection of high end power tools to build a house. Either will get the job done, but one is significantly faster and less effort. There are also things that aren't feasible using just hand tools.
Solidworks has insane simulation capabilities and it's used in aerospace for that reason. AutoCAD has extensive, mature, specialized toolsets. Fusion 360's ease of use is unmatched and its built in CAM tools are phenomenal.
I've used AutoCAD, Fusion 360, Rhinoceros 3D, and currently use FreeCAD. FreeCAD feels like a buggier early 2000s AutoCAD in an alternate timeline that went with parametric modeling from the start. I often have to use weird workarounds to get the geometry I want -- particularly to maintain absolute and relative dimensions on parts I want to scale. The dimension reference system is clunky, the toolset is limited, and the simulation capabilities are ... primative.
I put up with it because I'm a FOSS fanatic and I'm not designing fighter jets or spacecraft. If I had to pick a CAD suite for a critical or complex project FreeCAD (as it is now) wouldn't be a contender. I do think that will change and look forward to it.
