XAVC-S vs XAVC-HS - What situations is one better?

Now I had assumed:

HS = H265 = Smaller file sizes / better image quality, due to the more efficient compression, but takes more computer power to edit the files because H265 is more intensive.

S = H264 = Slightly larger file sizes / less retained details (marginal probably), but a bit easier to edit.

S-I = Huge file size, great details, easy on the PC.

I only have a V60 sd card atm so ignore S-I as an option. No problem there.

Because my PC is overkill personified, I figured HS would be a good choice. Smaller files for the sd card, and can just decode or convert them on the pc later.

Did some tests though... and the file sizes end up being the same in most cases, and sometimes the S files even end up smaller (which confused the heck out of me).

So now I'm wondering if it's a detail thing, such as 100mbps on HS gives the same quality retention as 200mbps on S, or some such thing (which is perfectly possible). However it's hard for me to do a decent test case for that right now.

So I figured I'd try asking here, as these comparisons have been around for at least a year or two due to the A7iv and A7Siii releases, so hopefully there's a comparison or something out there (I've tried googling and youtubing but found nothing, I suspect I'm searching for the wrong keywords though).

Appreciate any pointers!
