It may have evolved since I last used it. But when I tried, it was a bit of a "bag of spanners", thrown together shell scripts which made some incorrect assumptions. Back then it didn't even make a bootable device. Everyone seems to rave about it now though, so may be worth another look.
I had an old version of ventoy and it worked flawlessly for a long time. Recently it had some problems with booting an EndeavourOS iso, I updated it and that fixed the issue. Updating was just downloading fresh installer and clicking a button. For me it has always been solid, the UX of just copying over the iso and still being able to store random crap is perfect.
