But back to the original question... Given those two, take the Samsung. Quality wise the two are close enough to not make a difference. But the S7 is an speed machine.
I agree, and would submit that for most people, most of their vacation "snapshots" are going to be best handled with the S7 camera module as opposed to a higher-resolution smaller-pixel camera.
Yes, if you hold it really still and are in bright daylight, other cameras (even the one on my old Note 4!) can outperform the S7e in terms of "size I can print this on canvas and show it at an art show". So if you are going on a landscape tour and the forecast is bright clear sun, the V20 is the device of choice. It will capture more detail because it's a technically superior camera. You'll get home with some stunning landscapes.
If your vacation includes activities in the evening, the possibility of indoor photos, or the possibility of taking photos of moving subjects (or photos from moving platforms such as a bus or car), take the S7. Your landscapes won't be quite as good, but all of your other photos are more likely to be useable and less likely to be a blurry mess of "where were we when this was taken? Is that little Jimmy or the dog? I can't tell..." LOL
A 16 mpix F1.8 camera is a beast of a camera, make no mistake, and will win hands-down in any professional photo contest. But a 12 mpix, F1.7 can collect a lot more light per pixel a lot faster, and 12 mpix is still a pretty darned good photo if you are in the realm of "snapshots" and not trying to compete with a DSLR which comes with its own issues (size, weight, tends not to be stuffed in a convenient pocket when that magic photo opportunity catches you by surprise...)
