I used to have a pile of USB drives for this purpose, with various different images on them. I had a windows, linux and memory tester 86 plus and occasionally needed to flash something like clonezilla or gparted. Nowadays I have a fast USB4 capable flash drive which just does all this faster and a whole bunch more ISOs on it and does bios duty too.
One other small advantage is with secure boot you only need to register Ventoy once with a machine and then all the ISOs will boot, whereas with different USB sticks and images each has to be registered individually and some of them don't work with secure boot so you have to turn it off. Just another convenience.
