Altium Designer vs Allegro Cadence vs Mentor Graphics Expedition/Pads?

Question

Do it yourself

Please help me decide on the choice of end-to-end CAD printed circuit boards.
While I'm tinkering with Eagle + Axe. Not convenient: I change something in the circuit and it starts ...
From the wishes:
- a large library of components
- a good autorouter
- relatively easy to learn
- analysis of interference and mutual interference
- simulation (optional)
I would be grateful for a short review / enumeration of the advantages and disadvantages of each of CAD. What CAD system did you switch to and why.

Answer 1

Altium Designer. Simple, convenient, understandable, reasonable price. If you are interested in any specific questions on the use, you can write in a personal.

Answer 2

I will refrain from evaluating the rest of the CAD systems, since I do not have much experience with them. I will only say that in some deeper points, for example, impedance calculation, altium lags behind. And their price is higher.
