Does 7z compress better than zip?

In addition to directly compressing and comparing file sizes, Does 7z compress better than zip can also be compared like this:

Multi-type file test method
Instead of testing only one file, you can prepare a group of different types of files, such as:

Plain text (.txt)

Pictures (.jpg/.png)

Videos (.mp4/.mkv)
