difference between different downloads Windows 10 LTSC 2021

[Cixert]

I am going to install Windows 10 LTSC 2021.
I see that there is an official download evaluation and download partners to sell a loose retail license.

The Microsoft download and the SoftComputers download have a different size
https://softcomputers.org/en/download/distr-windows/download-windows-10/
All the files are the same except in the resources folder these 4 files:
-boot.wim
-EI.CFG
-install.wim
-PID.txt (serial key)

This contains the EI.CFG files
-Microsoft:
[Channel]
eval

[VL]
0

-Soft Computers:
[Channel]
volume

[VL]
1

I haven't looked at what changes in the boot.wim and install.wim files yet.

What difference do I have between installing one or other version if I am only going to buy a license for one computer?
Is it useful to download the Microsoft evaluation to buy a separate license a SoftComputers or others Microsoft partners?

While it's not a night-and-day difference, every little bit helps when it comes to squeezing the turnip.

I find 2021 LTSC to be slower than 2016 LTSB.

What do you recommend better LTSC 2015 or 2016?
Is it possible that these two versions will lose security updates before LTSC 2019 or 2021?

I'm afraid that I am not the one to ask regarding "security updates" - I never install security updates.

I run a contract business and use the LTSB version strictly to avoid "security updates" breaking robot controllers, camera vision optical inspection equipment, et cetera.

You can check the end of servicing dates first.

I spoke too soon in comparing LTSB 2016 to LTSC 2021.

My 2016 is heavily tweaked and runs 29 versus 51 processes (76% increase), 288 versus 622 threads (116% increase), and 8766 versus 21581 handles (146% increase) that a temporary LTSC VM runs for testing purposes.

2016 on the left, 2021 on the right.

A fairer comparison will be after heavily tweaking 2021.

Thank you.
I was confused with the end of service times.
The extended support was misleading me.
I am looking for cumulative packages, for these versions.
The Microsoft system is quite confusing, with long texts blah, blah, blah, that don't say much information.
On the web there is a history of updates:
https://support.microsoft.com/es-es/topic/historial-de-updates-windows-10-8127c2c6-6edf-4fdf-8b9f-0f7be1ef3562
For LTSB 2015 (v.1507) the last one that it brings is from April 2023, however, for v.1511 is on "end of service statement". The LTSB versions are updated.

For LTSC 2021 (v.21H2) it seems that the end of final support is in 2027.
But for LTSC 2019 it's in 2029. It's hard to fathom.
However, for loT Enterprise, based on LTSC 2021 is in 2032.
Is it positive to use Windows 10 loT Enterprise as a workstation?
