What EDA do professionals use usually?
I will probably be outside the norm, but KiCad, I work with automotive electronics for Bus and Truck

Cost of teaching was a factor, those expensive packages tend to have about a 1.5 month learning curve to really explore all you can do with it, and for that time and cost It was easier to learn how to accomplish similar results without quite as much polish with the tooling I was already familiar with, since then, other employees have been trained with KiCAD as well, as they did not have any strong preference.

e.g. what might take 5 Minutes setup + 2 minutes action in altium, may take 15 minutes to just hash out in KiCad, and over time that may add up,

When you get into things that are too complex for a single active designer to handle on their own, then your forced towards the more expensive packages, e.g. multi-room, so multiple people can layout the same thing at the same time.
