rufus is good for preparing a windows bootable usb with uefi boot (so you can later enable secure boot, after install), so stick to that. ventoy is great, might be better than rufus, when you want multiple os's on a stick, but for the average person it's also way more complex than rufus. (rufus only works on windows tough)
Could you point to some good sources that explain in detail the whole "bootable USB" world? It seems it's always a hassle to get right, especially when preparing a Windows bootable USB.
