Beats the tinkle out of me, maybe because a fresh reamer gives a better surface finish.
On the occasions when I use a reamer, I am looking for a straight hole with a decent finish. A sharp reamer will produce a really nice finish but it won't produce a consistent size or finish if the hole is not straight first. When it matters, like with a boring bar holder, I will drill to rough, bore to size and straighten and then ream to finish. Works for me.
