It is similar though, but yes it misses the "more ISOs" part, which I actually find weird because at that point that would be almost cheap to do - that's why I did not reverified that bit, sorry.
Unetbootin either dumps the raw ISO directly to the block device or, in the case of Windows, extracts it to an exFAT partition. Ventoy doesn't require you to extract or dump the ISOs at all, which is where the real beauty of it lies.
