All the PCB designs that I’ve been exposed to professionally, both in-house and at customers in Taiwan (think ODMs for Acer, Asus, …), were designed with Cadence Allegro. These are all complex designs with high-speed interfaces (PCIe, DDR5, …), 12+ layers etc. Ironically, It’s only when I started doing hobby electronics that I learned about the existence of Altium. (That’s not a value judgement of Altium, I honestly don’t know how they compare.)
