Hello! That is a really good and tough question. I would probably have to pick feruchemist, because theoretically anyone could become a world hopper, and it seems more useful in day to day life than being a Mistborn or a Windrunner, whilst still being able to hold its own in combat. Being able to heal with storm light would be pretty cool though. Also feruchemy is the one thing on this list we don’t know how to get without hemalurgy so there is a chance one could become all the other things, though it is highly improbable. I also just remembered, being a feruchemist would likely place me on scadrial, which has working plumbing.
