I much prefer using a formula based tool to make packages for a specific part's mechanical drawing, I just don't trust what other people have made yet. I'd like to be able to but the trust isn't there yet.
Maybe kicad could list parts as verified against a standard footprint based on user feedback so that I know that whatever random part number actually fits this particular soic wide or whatever bga pattern. Maybe a part number has no notes but it's nice to know that no one has checked it manually yet too. Like the wine database.
Maybe it already exists, I haven't found it yet.
Unfortunately, companies like SnapEDA bring negative value to the industry because they produce crappy libraries that you can't trust.
So, they reduce pressure on the parts vendor to produce a decent symbol/model. At the same time, I can't trust the symbol/model until I check it personally and run it through a project. And, finally, some contract terms generally prohibit me from redistributing that symbol (go check the terms you agreed to when you signed up).
SnapEDA and their ilk need to die in a fire.
On top of the other answers: a much more friendly UI. Blender used to have a horrendously steep learning curve because the UI was just alien and ignored most agree-upon convention used by other 2D and 3D packages.
Not the case anymore, Blender is much more user-friendly and beginner-friendly.
The huge amount on online video tutorial also helps tremendously.
That way you're climbing the "using the tools" learning curve separately from the "laying out designs" learning curve, which makes it all a lot easier.
Orcad is, I dunno the Catia? Was the "serious" software back in the day so preferred more by greybeards who scoff at using amateur stuff like Altium. Interface is much more dated and less intuitive. A company I worked for had a mild mutiny because they hired an Apple guy that insisted that everyone learn and switch to Orcad and the EE team just balked at it.
If Kicad can catch Altium on usability and handle dense, complex boards then it could be the best package out there. Just the fact that they actually fix bugs puts them at an advantage. They may already be there, I haven't played with it in a while since I'm at an Altium shop.
