Aside from lighter and perfect offset as mentioned, IMO (which is just that of course, an opinion) they simply look better. I don't care for the somewhat rounded spokes on the VMR's for a boxy car like ours. I think the flatter spokes of the Apex's just look better matched. And they recall the classic BMW BBS spoked wheels to an extent as well, without flat-out trying to duplicate them.
Better function + better looks = win.
