Basically, VSF has this genuine feeling when you hold it, bracelet is a lot better than on a Wu one, it opens a lot easier than Wu but Wu isn't bad tbh.
Bezel color is a lot better on VSF, inserts on Wu Sub are too white, bezel also sounds amazing on VSF.
Wu dial has some imperfections, floating letters, not correct thickness. Dial on VSF is perfect, I can't see any flaws. Also, Wu has SEL flaws, but very small and not noticable at all.
VSF has a silent rotor, can't hear it at all, rotor is pretty loud on Wu but only if you shake it, it won't be noticable on hand.
Rehaut is wrong on Wu Sub, but you can't expect perfection for 100$. Winding is very smooth on VSF, worse on Wu but not bad at all.
Lume is totally wrong on Wu Sub, it is blue but should be some kind of a green-ish colour.
Overall, I recommend investing more and getting a RepTime tier watch if you are going to wear it everyday, but if you want to get a good looking, cheap watch that you won't care about then I recommend getting one from Wu or Jason, It really is impressive for 100$
