Greetings from Holland. After owning a GR2 and a GR3, I sold the GR3 and noticed that I no longer go out on the street, not even with a Fuji x100vi. So, I bought a GR Street again, hoping that the feeling will come back. At least it feels familiar again.
As you realized, the GR is like a drug. You can not live without it, no matter what else you use.
I use many different systems, but the GR is irreplacable with something else. I sold my X100V again because of thr GR3/GR3x. It just could not keep up with the GR3.
