In wood working, one would call those stay eye caps "proud". I'd be proud to have some of those on a bike. IN spite of the fact that I couldn't resist the wordplay, it is a matter of style. I really dig those old LeJeunes with that style caps. It is not easier to do, if anything, it is harder to do well. On a production basis, when one has done lots of them it may eliminate a few minutes filing but to get it even would take some doing. Still, just so I don't sound closed minded (I am, but don't want to appear that way), I should say that it is preference and is open to personal judgment.
