I can tell you right off the bat that POSIX might be better than no "standard" at all, but porting stuff between any POSIX-ish OS still means an actual port.
Practically every non-trivial POSIX-ish program is not portable. This also includes quite some supposedly higher level applications written using things like Java, Go, Ruby, Python ... since they all leak POSIX details all over the place and make non-portable use quite easy.
