I know they've been obnoxiously chipping away at the features available in their Personal edition and introducing artificial limitations. But my free installation still works and I haven't seen any indications that it's going away.
Fusion as a CAD engine is great. I've not used the CAM side, and while I used to use Eagle a lot I've tried to invest more energy into Kicad. The online limitations are frustrating though. Randomly and inconsistently not being able to export STLs because of a "translation service error" (when it could 2 minutes ago), or the inability to make drawings with the free edition. I mostly use it because there isn't anything else half as good for OS X that works offline.
I used it to do some sheet metal modeling, then sent the models off to a laser cutting/bending service that shipped me the pieces. Then I went back to Fusion to 3d print some brackets/scaffolding using the same sheet metal models as a reference, to assemble the pieces into the finished product. This was during a 3 month leave from work, starting from zero knowledge beforehand. It was probably the most fun I've had in years, and mostly thanks to how slick Fusion is and how many tutorials there are out there.
There are some export formats that it uses cloud machines for, which I think is silly and arbitrary. It's probably done that way to upsell their premium product for faster wait times or unlimited quota. For my uses I was able to select formats that didn't require the cloud.
Fusion is much more polished compared to FreeCAD and so I'm not sure if I'll ever end up making the switch. But I'm glad to see a free alternative, just in case.
Most of the common translation options should work offline (ie Fusion is capable), but Fusion sometimes gets stuck in a weird state where it insists it needs connectivity. Perhaps it's a quota thing but I've never found it to be consistent. This happens fairly often with STLs for 3D printing.
Once it's gotten into that hole it will often refuse to export any other format until connectivity is restored, even if the app is restarted. It's known behaviour, for example the official guidance is that changing binary to ascii might help, or you shouldn't export directly to a slicer when offline, or don't use certain menus. But it seems like a wontfix.
Fusion 360 CAM is great for me (hobbyist doing CNC with wood and other materials). It's handled some pretty tough jobs, like a full topo map of california. It's why I pay for the product. I tried the electronics stuff in Fusion and decided not to use it because it didn't work nearly as well as Kicad.
