The Pico 4 is actually a really good headset. It's not officially released in the US market, but can be imported from EU sellers, which is how I got mine. The resolution is pretty good and good enough to replace a monitor, imo. I've used it with the Immersed app and liked it. It's also really small and light compared to other headsets.
The Pimax Crystal has great resolution and virtually no glare, but it is too heavy and bulky to wear for extended periods of time.
At work, I have setup and support the Meta Quest 3. It's also a good headset, but I don't feel compelled to get one at all. The visuals comfort are on par with the Pico 4, but the Pico 4 is cheaper and not dragged down by the Meta software. Though, it should be noted that I use it for PCVR almost exclusively with Virtual Desktop.
