I guess this is a poll for just Sony fans on the site, rather than to get polling data on the whole site, because you didn't include a "not going to buy it" option. I supposed the bottom one is the closest thing.
There have been a number of factors, over the years, for why I have never bought Playstation hardware. But there is one reason, above any, of why I refuse to buy their devices. I cannot stand their controllers. They feel awkward in my hands. And they aren't the only console maker that creates uncomfortable controllers, I hated the N64 controller with a passion and now, in retrospect, I cannot stand Wiimotes either. I also hated the original xbox controller, and I'm not terribly fond of the Joycons (though the portability factor outweighs my dislike, and when it's docked I play on the pro controller which is great). But with Sony, they consistently make controllers I hate, whereas other companies are hit and miss. I hated the PS1-PS4 controllers and I'm fairly certain the PS5 will be similar to their past, which is great for people that like it but I just can't get over my hatred of how awkward it feels in my hand. But who knows, maybe they will update it enough to get me liking it.
You'll be happy to know that there are over a dozen different controllers for the PS4, so you can go buy one now xD
