Post History

I will try to cover additional aspects.  

Not eager on making changes - Big organizations are usually non very prone on changing their horse for the battle - sticking to their EDA choice from 20+ years ago. Doesn’t mean they would repeat it today. 

Pricing -  I am yet to find the company which paid the full amount for EDA tool - the bigger you are, the easier your negotiations would be. We halved the Altium price without putting too much effort in it. Other well known alternatives have been priced much much higher(x3 and x4). The “benefits” they are bringing are not beneficial to most designs I have seen. 

PLM/ERP - One other aspect is integrability with the rest of the organization. Product Lifecyle Management, ERP integration etc. is something that you pay in addition bur are needed if you are big player. 

If you are sole designer or small organization, go with whatever pleases you or you have money to pay for. 

I know, knee-jerk reactions are omnipresent. Ignore the noise and focus on what really matters.
