Which is better WIM, ESD or SWM?

Which one is better in terms of ISO quality, no file loss, special changes, etc.
Note: "I try to make the ISO as good as possible." and "And even though I'm searching, I find myself confused, skeptical, and unsure of the best option."
 
100 or 200 best ISO for outside pictures on a sunny and bright day
400 ISO for cloudy days, or indoors for window light portraits
800 ISO for indoors without a flash
1600+ ISO for really low light situations – that school play your kid is in

But seriously computer ISO's I don't find any big differences in them as long as they work. Some compress more then others so it is all up to what you want. This is just me
 
Unlike the last skeptic who asked this same question twice, there is no difference in quality.

All WIM formats are lossless. The possible compression modes are:
- none (never used)
- Express (default WIM compression)
- LZX (compact mode)
- LZMS (ESD compression)

SWM is for legacy reasons when you need to split a WIM across multiple media because it doesn't fit as one file. Just like splitting a ZIP file into smaller chunks. With generic USB sticks > 8GB, this is no longer used unless you're updating old PC's with no USB, and only a DVD drive.

For downloads or the final install, ESD is preferred for its smaller size. ESD format cannot be used for editing, and must be converted to normal WIM format. When finished, you can convert back to ESD for deployment.

PS - I would recommend iPhone 14 Pro for your kid's school play.

Default WIM compression is LZX :)
None (Copy) method is now used for the LCU msu file (now a wim file instead limited cab) for canary builds 25336+
xpress level was used with Windows 8.1 wimboot files

i guess the main reason for split wim is because FAT32 cannot read > 4GB one file, and MS only allow FAT32 system for UEFI usb installation (i think they added support for NTFS in Win10 v1709)
