I don't think GNU/Linux is that tricky, but to a non-techy person that might be difficult. While using Windows I would have recommended Rufus because of its differentiation between EFI and mbr options during creation.
Ventoy is advantageous because you can store multiple .isos on one memory stick. I don't use Zorin as my daily driver. It (Ventoy) also has a MOK enrolment key which came in handy when I had to install Linux Mint on a client's Acer notebook that had Windows 10 on it previously.
And in respect of Zorin 18 I have ditched Gnome for Plasma to replicate a Windows 10 feel which Zorin does not have.
