Should I buy Win 10 Pro ESD or OLP from the company?

Question

Windows

The bottom line is this: you need to purchase Windows 10 Pro for 60 laptops. Now there are pirated versions. ESD costs 8900r, OLP 11500r.
Here I did not find answers to several questions: is it possible to buy ESD in a company? (IP). Can ESD licenses be transferred to another laptop in the future?
There is also GGK, but it is the most expensive and you can’t transfer licenses, but you don’t have to reinstall the OS
