Just to set your expectation right. Whether its lens based stabilisation or sensor based stabilisation, it wouldn't fight the physics where if your subject are moving, they will be blur unless you use fast enough shutter speed to freeze the images.
There are so many lens for Nikon or Canon or other branding out there with in-lens stabilisation if you really so need them. I have so often work with 24-70 f/2.8 without any stabilisation at all and when in focus, all my images are sharp.
When at night, use a tripod or monopod. Image Stabilisation will do very little good. The only time I really find image stabilisation really useful is on my 70-200 f/2.8 when on the long end.
For Optical VF, in-lens stablisation is the only way to observe stable images when the stabiliser is active.
For EVF, sensor stabilisation works since you will never see through the glasses with your naked eyes.
In my opinion, OVF are more superior than EVF because at the moment, no digital sensors have better exposure dynamic range than our pair of human eyes. I see more things in the dark with my pair of eyes across the OVF and hence makes better judgement in composition compared to the noisy EVF in low-light condition.
