This question is confusing but perhaps it is because Windows editions are confusing. See here: http://www.techrepublic.com/article/windows-10s-seven-editions-are-excessive-see-which-two-id-cut/
But ultimately if you don't like Windows 10 home you won't like Windows 10 Pro, it will be almost indistinguishable to you from Windows 10 home and if you prefer Windows 7 to Windows 10 home then you will also prefer it to the pro version, as the UI is the main reason you likely don't like it and the home and pro versions have the same UI.
As for whether 7 is better than 10 I prefer the UI but recently switched my Windows virtual machines to version 10, as it can run all that Windows 7 can run (except old outdated browsers etc) and can also run newer software and will be supported longer.
But if you don't like the UI the pro version is not gonna help that. My personal preference is for OSX, and I have MS Office there and virtual windows machines if needed.
