In comparison to Xbone which only has Halo since Gears of War and Forza are now available on PC? The games i've listed above would justify the price tag to get a PS4 to experience those games itself.
Hardware and performance wise the Xbone may be better but for me and many others will recommend the PS4 if you want to play exclusive titles.
Exclusives is what wins in the console market in my opinion.
People will buy a Nintendo Switch to play Zelda alone, some people will buy Xbone to play Halo like myself at the time and I bought PS4 for the wide range of exclusives and I am fan of the niche/japanese titles like Gundam Versus Extreme, Jojo Bizarre Adventure All-star battle and Fist of the North star.
Of course its worth it for some people who are eager for a few specifics off that list. There is no doubt about that. But how many of those games are truly unique? A lot is 'yet another sequel' of which similar games or even the franchise is available on other platforms.
I mean going through your exact list, I have seriously considered all of those titles and yet only Horizon ZD had some sort of system seller effect on me, yet wasn't enough. Bloodborne did something similar, but really, with Dark Souls emulation/ports on PC, who cares. A game like Sekiro, for example, also got a PC rendition. There is just so much on offer that is very similar to what was a PS4 exclusive, that I just don't feel any urge to play on a low performance piece of hardware that will cost extra money.
Now compare to PS2 and PS3. A lot of games were truly platform exclusive, simply because input device was unique (sixaxis, and for PS2, it was difficult to emulate on PC for a long time) but there were also types of games that you'd NEVER see on PC in any shape or form. Shadow ot. Colossus, Okami, are good examples. The PS2/PS3 also had some first party stuff that was way ahead of its time, such as Heavenly Sword, but also the earlier God of War releases.
PS4 can be forgotten quite easily and you wouldn't miss a SINGLE true masterpiece or real classic-to-be. Let's just face it. There is a lot of 'good' content on it, but not a single one has redefined gaming in any way. Its just more of the same. Even Horizon ZD was just 'another open world game', and I hear remarkably little about it now - I hear much more about a similar game like The Witcher 3 (that was even released longer ago). That captures it nicely I think.
I do agree completely with you about all the rest, because yes, console choice really is all about the content you want on it, not the relative performance or anything like that. Still strong Sony supporter for doing what they do in terms of content creation and funding, too bad the console ecosystem is detrimental to gaming as a whole.
