It really is a toxic argument and typically both sides have a share of ignorance to their supporting reasons why one is better than the other. However, console fanboys typically are far more ignorant when attempting to bash PC players.
In a logical, everything on paper sense, PC is far superior to console, it's not even a competition at this point. Also consoles themselves are getting more expensive as time goes on. So in the end, the whole "Console is cheaper" argument is slowly becoming invalid as soon enough the price to play on any platform will be the same.
My argument has always been this: Don't build a PC to game, but if you need to build a custom PC, build it for gaming. Initially I built my PC because I use Unity Game Engine, Autodesk Maya, Blendr, Keyshot, Zbrush, and Adobe Master Collection 6. So I built a gaming PC for even though these programs are demanding, they are nowhere near as demanding as most games today. So by building a rig that could run any and all games at ultra settings with over 60fps means it can do my everyday work tasks as well.
With that said, I also own a Xbox 1 and played on a 360 for many years, I play D1 on PS4, and even just bought a Switch as well as owned Wii and Wii U because I needed my Mario fix. Each and every platforms brings something unique to the table and I can understand why someone would choose a console over a PC, but we all know there's no denying that a PC is far more superior in every single way.
