These are good, but I would argue that the bolded go for PC as well.
PC currently has:
More exclusives than all 3 current consoles out combined
More local multiplayer games (Fucking crazy right?)
Actually, you should think about consoles OR PC. All platforms have games that can't be obtained or played anywhere else. Though emulators somewhat mitigate that on PC.
My point is slightly vague, I apologize. There are likely arguments for or against every single bullet point listed as you point out, and as the tree in OP's post points out.
If you are passionate enough about video-games to the point at which you browse forums, have opinions about issues such as the state of the gaming industry or something else, you already are way more into video-games than anyone else. People like us are the minority, not the majority.
In that fashion, the same people who look up benchmark videos and console war videos on YouTube and comment on them belong to the same community people who are passionate about video-gaming. Then, it becomes very likely that these people who care about video-gaming also care about "the best experience." Hence why console wars begin and why PC vs Console debates exist. And just like any debate, there are radical opinions on both sides and people who want to vilify their own opinions, logical fallacies thrown around everywhere and it becomes a figurative shit-storm.
I simply try to make the point that if you love video games, you'd love them on any platform. Just look at the pros and cons that appeal to you.
The problem is that these arguments boil down to "nuh uh" and "yuh huh" which makes it impossible to make a reasonable judgement.
Gaming websites like Kotaku and the (actually hilarious, you can pay to publish an article on Forbes) articles on Forbes are heavily biased on the author's own preference. So one day, Kotaku (for example) may make a claim saying that PC is way too expensive while the next day, Forbes writes an article teaching people how to build a budget PC that can outperform consoles. Neither article is likely well-researched and understands every pro and con and I doubt they deign such nuances as even slightly important - clicks and clickbait is the way to go. Few truly unbiased videos exist, even fewer unbiased opinions.
As unbiased as I try to be, I still feel that I will always be biased towards PC gaming. And no doubt there are enough who are biased towards consoles.
If anything, I don't want to convert anyone. I just want to provide a better source of information for those who are new to all of this, new to loving video games, and wondering where to go next. There are enough people like me in the "PC Master Race" as well and there are also enough people like me on ConsoleGAF. And yes, I am passionate enough about video-gaming to the point where I'd type out multiple large paragraphs to support my views.
