VR/IS is only getting better and better. It's really kind of nuts.
Even my first gen 300mm f/2.8VR I'm constantly amazed that I've gotten sharp shots handheld at 1/125 with a 2x TC, and that lens tends to make my hands shake more than even something more moderately sized like a 70-200 2.8 would.
In lens+in body on my X-T5 is unreal, and I don't think it's exactly unique in how well it integrates the two types of stabilization(letting each handle what ti's best at). Using the 16-80mm f/4 lens I bought it kitted with, I have managed 1/2" reasonably sharp across the entire FL range. I don't make a habit of doing that, but it's good to know it's an option.
Of course with anything it's worth testing. Thom Hogan found at least in earlier incarnations of Nikon's VR, it could often hurt sharpness at high shutter speeds. I forget exactly what his range was. In practice, I do often turn it off when my shutter speeds are in the 1/1000 range or faster. I have two lenses with Nikon's first generation VR system-generally identifiable by a brass plate on the lens that IDs what it is, often the letters VR highlighte d in red, and in use they have a comparatively loud "hum"(and also tend to clunk around a lot more than newer lenses). I'm really cautious/selective with whether it's on or off on those lenses. I tend to forget about it on my 24-70 f/2.8E, primarily because I can't hear it(I suspect that newer systems operate at a much higher frequency well outside the range of hearing). I have a few other VR lenses, but those are my most used ones(along with the X-T5+16-80).
