Windows 11 is pretty similar to Windows 10, you can try it out and see if you like it, as the other commenter has said if you don't like it you can roll back within 10 days (that's if you do the in-place upgrade and not the clean install).
Be sure to check that you have TPM 2.0 in your bios, you will need that enable for Windows 11 due to security.
Also, if you don't like the UI of Windows 11 but would still like to keep it you can use an app called 'StartAllBack', this app brings back the Windows 10 style taskbar which is useful for people that don't want or cannot adapt to the new Windows 11 design.
