Console:
- relatively flat pricing
- game performance can be measured definitively across each title and set in stone by the developer without user needing to adjust -- even if they are performance limited compared to what the PC spectrum is able to provide
- "upgrades" are rarely needed to keep up with the ecosystem (and if they are needed at some point, they're cost-competitive to PC component upgrades)
- OS updates are maintained and delivered in a relatively unified fashion, console manufacturer issues OS updates and game developers can issue updates for games individually
PC:
- pricing varies dramatically depending on the performance the user wants
- performance varies (potentially quite greatly) based on components assembled; relative performance expectations require at least some semblance of understanding of contemporary game engines and game settings. I think people who are in the know on this stuff take for granted things like knowing that MSAA requires more system resources to utilize than FXAA, etc... and having someone (developers) just predetermine all of these variable settings ahead to reach a set performance goal is generally far more convenient, though not always optimal if you do know these settings and their effects on the end user experience and you develop preferences based on it
- routine maintenance of PC through various forms of updates (updates for games, updates for game clients like Steam, updates for Windows, updates for specific PC components like GPU, keyboard, mouse, etc...)
- lack of understanding of certain settings or game engine functions can lead to pretty easy misunderstanding of why games are ultimately running the way they do, and PC's user-customized experience can make this an extremely overwhelming prospect when you've bought into the hype cycle of a game's marketing, review cycle, or positive word of mouth but your excitement to get to the game is being stifled by puzzling technical issues that you lacked the understanding to foresee or address. Someone on a message board telling you that your new PC has approximately 5x more processing power than your console of choice but not knowing how various PC-only settings weigh in on that processing power can lead to some very puzzling and sometimes frustrating expectations v reality outcomes
- the lack of understanding bit above has you going to forums seeing people with various specs, sometimes ones that are theoretically close to yours, reporting non-issues; you also get exposed to people having much better specs in the same reports and maybe start to lament not waiting longer and budgetting for a better CPU or GPU or both because of the bevy of positive responses that report no issues while you struggle to comprehend, sifting through message after message, etc; you do this for years and years and realize that new CPUs and GPUs come out every 1 or 2 years and they seem to get incrementally more expensive so you always feel like you're behind, and that feeling just gets exasperated by your inability to comprehend where things went wrong once or twice in completely different games for completely different reasons, etc
PC is probably like 90% hassle-free, but that 10% has a tendency to snowball for anyone that came from that console experience.
