I would advise you to switch to Windows 10 for now, I am sure you will not have a long period of adaptation and in just a couple of days you will be fully accustomed and enjoy working on the new system. As such, there are no particular changes between Windows 7 and Windows 10. The functionality remains the same, except that a little extended.
To compare two largely different operating systems, you need to look at a number of parameters. This is the only way to determine the favorite.
Moreover, in many ways, the conclusions will be subjective. Those who are accustomed to Seven will argue that there is nothing better than Windows 7, and Ten with its new menus and design is extremely inconvenient. And fans of Windows 10 in response will say that the ten has become advanced, multifunctional and efficient.
I switched to Windows 10 three years ago and have never regretted it. By that time, the company's experts had already managed to eliminate frequent bugs that users encountered, to make some changes, that is, the system was already fully operational.
As for my transition to Windows 11 personally - I have the opportunity to do so technically. All the parameters of my laptop allow to do this, but I decided to let the programmers of Microsoft to improve this undoubtedly wonderful new system without my participation))) I think in a couple of years, or maybe sooner, when all the shortcomings will be eliminated, I will join the group of owners of the operating system Windows 11.
