It was great at the time, hard disagree now.
The resolution was one of the first things people would complain about in those days was how blurry it was. Being able to make things out in VR is a game-changer, and the Quest 3 just happens to excel at that.
1080 x 1200 pixels per eye
2064 x 2208 pixels per eye
On top of that, I would argue the pancake lenses are equally a huge gamechanger along with the resolution. So 2 massive indisputable advantages.
Not to mention 90fps vs 120fps, wired vs wireless/portable, easier tracking solution, smaller controls, lighter, standalone library of 500 games no PC required, but also better at PCVR, MR, much smaller profile, cheaper. The whole experience is much easier now on top of all the other advancements. Quest 3 you can easily see your surroundings. I mean, the advantages almost never end. I probably forgot half of them.
Even though the setup wasn't bad at the time, it's just a whole different experience now and much closer to a console plug and play.
Vive:
Quest 3
You literally just press a button and put on the headset. Not to mention, the standalone games in 2024 will match what was available in 2016 PCVR graphically. You could argue Assassin's Creed comes close now.
