QUCS is nowhere near equivalent to Microwave Office or ADS; those each have well over 100k man-hours of code development. Harmonic balance, transient for distributed circuits, envelope and system simulation, layout, 2D and 3D EM, and hundreds of models, all tightly integrated. Not to mention all the MMIC and RFIC PDKs.
It’s fine for hobby use, but if you need to make $ and get designs out the door, you need to use the real stuff.
I tried KiCad, but using Altium for 25 years, it just doesn’t have the functionality I need. Lacks basic things such as assigning nets to arbitrary polygons, which is a must for RF.
