I haven't used Kicad in years. I thought they improved significantly in that time span, while HorizonEDA was stagnating at it's admittedly very good level of quality.

What I am missing from HorizonEDA is the ability to set constraints to signals/pads such as maximum and minimum current, voltage, frequency or setting impedance targets.

There is also no easy way to do a simple static current FEM simulation on custom polygon shapes. You can already do this using a chain of four open source tools but it is a lot of manual steps.

I am repelled by the notion that software requires a constant stream of tweaks to be healthy. If you look at the issues on GitHub, there are basically no open bugs there; it's all feature requests.

You can set a net or net class to have a set of geometric constraints suitable for a particular impedance or current or voltage. This matches or surpasses the capability of every other EDA software that I've used.

I also think it's unreasonable to ask EDA software for a full on FEM simulation. You wouldn't want to do that with the full board geometry anyhow.
