KiCad is frustrating because it’s actually good enough to make a lot of models but it’s just unfriendly enough to make it take way too long to do… but it’s also still way easier than learning how to do it in a full-featured cad program.

I would kill for something like KiCad with more refined controls.

I can second Horizon EDA. It's not perfect, but it has the good KiCAD kernel without the abysmal UX.

FreeCAD may also be good - it's the only other one I haven't tried.

On the other hand if you're convincing EAGLE users to move they'll probably be happy with KiCAD because they're already used to an even worse UX, as if such a thing were possible.

There's HorizonEDA. Just be prepared to spend a ridiculous amount of time setting parts up.

I wish KiCad had a constraint solver built-in for defining footprints and placing some key parts of a PCB. A better library management system would also be nice. That aside, I think their interactive router is pretty great, and a huge improvement over older versions. I first tried KiCad in 2016 or 2017 and routing traces was pretty dire, especially if you had to redo them for whatever reason.

Got any specific pain points for KiCad?

Autodesk should have started their own ECAD from scratch. They have mountains of CAD know-how in house. Their acquisition of EAGLE did nobody any favors.

I am not sad to see it go. The only ones I know of who used to use EAGLE were those who got hooked on it when it was either free or the cheapest option for hobbyists and small businesses. It didn't win any UI/UX competitions, certainly not against the joy that is modern programs for solid CAD.
