I have watched a lot of comparison videos but went for the Quest 2.
Because the Quest 2 has better software support. It has some nice games not on Steam like Stormland, or Lone Echo, or Oblivion Afterlife.
And the picture quality is really good, I can clearly read all the cockpit labels in DCS and Flight Simulator 2020.
The Pico has literally the same disappointing field of view. Yes it has some fancy pancake lens motors but whatever… the middle setting should fit all eyes in the Quest.
The only advantage the Pico 4 has it´s not so heavy on the front. You absolutely need to buy the Elite Headstrap with the counterweight on the back, otherwise the Oculus Quest 2 will get unbearable uncomfortable over time. With the Elite Headstrap it can be worn for an infinite amount of time without ever becoming uncomfortable.
With the Elite Headstrap it is so nice and comfortable to wear.
I would only have considered buying the PICO4 when it came equipped with OLED screens and way more broad field of view, but it uses the same LCD technology and it has the same field of view so there is no more real advantage over the legend itself, the Oculus Rift (alias “Meta Quest 2” but it will always stay the good old OCULUS RIFT for me!)
