At last, something I have some knowledge about.  R8 is a very popular milling machine taper (at least here in the US).  A shop I used to work in had an old (ancient) Bridgeport mill with a morse taper, but most of the Bridgeports and their clones use the R8 now.  The R8 is a self-releasing taper (the Morse usually requires a blow to the drawbar to release it).

Personal preference:  If you are using it primarily for milling, go with the R8, and if the application is primarily drilling use the morse.

What do you think of R8 vs #3 Morse? Is one better, or easier to find
than the other?
