Reading the comparison websites is frustrating. As mentioned before, very few update their pages with firmware improvements. Both bodies have been updated a few times but the reviews are comparing five year old cameras with 1.0 firmware.
Worse yet are the features not mentioned! The z6 beats the s6 for landscape use on one site, but no mention is made of the s5's hi-res capability (48/96 Mpix). That's pretty valuable for many folks!
Also: internal stabilization is checked off for both bodies, but I've seen the Lumix give very impressive results and comments on most reviews rave specifically about Lumix' stabilizing prowess. And the aspect ratios are much more versatile on Lumix than.. well, Everyone, including Nikon.
Another vague area is lenses. Total lens count is pretty useless between mounts, especially since my preferences are for 20-xx and lightweight telephoto zooms (availability for L and Z is 0-1 and 1-0, respectively). Aarrrgh.
The other issue is resale value. I'm getting a nearly straight trade of s1 and s5 * - but the z6 has some scratches and marks on the big screen. I don't see the marks when the screen is illuminated, but prospective buyers practically demand an unmarked screen. This swings the value factor toward the z6. But can I tolerate the flimsy feeling of the z24-50, videos locked to 16:9 aspect ratio, and stills also with fewer ratio options?
Once the S5 is in hand, that question will presumably be answered. Sure hope so!
* Mostly due to s1 grip and spare batteries!
