I use PCAD - Altium's sort-of predecessor (actually started off indepoendent as ACCEL, got bought by the then-Protel, which morphed into Altium, I think...). When they announced they were discontinuing it a couple of years ago I did a last-time upgrade to the 'final' version. The sales guy kept pestering me with special deals to upgrade to Altium but having tried a demo version immediately took a dislike to it as it appeared hugely bloated with stuff I was never going to use - all I need is a simple, reliable PCB-only tool, whearas Altium seem to think that a huge megalith which does everything from PCBs to mechanics to FPGAs to re-tiling your bathroom is the way to go, and they don't care if that's not what their users want.
When I told the sales guy I wouldn't even be interested if it was a free upgrade he stopped bothering me....
