The choice between “v” and “u” is pretty arbitrary. “V” was easier for inscriptions because of the straight lines but in Latin cursive “U” was used as a more rounded form that’s easier to write. What’s inconsistent with ancient usage is the mixing of V and U. I’ve never understood why we kept V but got rid of J. It would make more sense to distinguish either both or neither.
