I second this.
While "The Go" has some great VR experiences like Face Your Fears and The Diary of Anne Frank, and it's a media beast, it's pretty weak compared to the PSVR.
My Go is mostly for watching movies and videos (which it does better than the PSVR) but it's like comparing a PS1 to a PS3 or an early PS4 when it comes to games. I do find myself using the Oculus Go more frequently, though. Mostly because of ease of access. Just grab it and you're in VR in two seconds.
This is probably the first reason I'll never consider getting a 1st gen PSVR. It looks cumbersome with cables coming in and out, and chunks of plastic all over the place! That's the last thing that I want in my room.
