I've had a PlayStation ever since the original PSX. At the time I wanted a Saturn because I had a Mega Drive and it seemed like the next logical step, but the Saturn was more expensive so I compromised and got the PlayStation. We all know how that went down, so in hindsight I was pretty glad I picked up the PlayStation instead.
Then over the years, I kept getting the new consoles: PS2, PS3, and PS4. I've felt that PlayStation has always had the best exclusives among it's peers. I've never been too interested in the world of Nintendo (although I sure played a lot of Zelda on GameBoy when I was young), and as others have pointed out a lot of the Xbox games seem to end up on PC (pretty happy about Halo Collection coming to Steam BTW).
Having a PlayStation combined with having a gaming PC has always kind of covered all bases for me. If I want the ultimate experience from multi-platform games in high resolution and crazy frame rates, then my PC in all its glory is there. If I want to couch it for a couple of hours and play whatever the latest PlayStation exclusive is, the PS5 will be there.
