is this cheating?

I found a dealer who will swap my S1 for an S5. Maybe not a precise match financially, but close enough to persuade me. So now the battle becomes a tag-team match!

So - what changes?

1. back to a swivel screen.. but
2. the other S1 positives* are here, plus better battery life
3. the high-res S1 viewfinder departs (which explains #3)
4. oops, this table doesn't show the Big One (PD vs CD autofocus) !!
5. the lens problems remain (L tele, Z wide)
6. the weight advantage is gone (well, almost)
7. I regain live-composite capabilities (never used.. but I have plans!!)
8. (theoretically) better low-light AF

I am forced to admit to myself that #1 and #4 were not major factors in the S1/Z6 battle. Also the Z6 (with en-el15b) battery life was a concern, and the S5 opens that gap a bit more. Really though, a 15c battery makes the gap far smaller! And just to show how reviewers think, the 'vastly superior' PDAF of Nikon and others comes with its reputation for 'some banding with pushed shadows' - the No Free Lunch principle in full display.

So - we'll do the swap and run a few more tests before calling this over. The primary driver of the next tests will be the viewfinder with manual-focus lenses. I'm using different ones now with the one-touch zooms in play, and that might be less of a hassle with the S5 than my previous time with it.

I was disappointed that I'm like everyone else who handled the S1 and called it Too Big. After the K-1 you'd presume I can learn from past experience; we'll have none of that, now!

* aspect ratios of all sorts, stronger IS within, 4k/6k, dual memory cards .. and the 20-60mm lens that I apparently cannot quit
