Comparison between BauerBodoni and Century Oldstyle

First, both are serif typefaces. Century Oldstyle has teardrop terminals on letters such as a, c, f, g, j, etc, whereas BauerBodoni has ball terminals. There is higher contrast between the modulations and the stem weights of BauerBodoni than in Century Oldstyle. Century Oldstyle has bracketed serifs, in contrast to BB's slab serifs. The x-height of BB is shorter than CO and the set width of CO is wider than BB.

Because of all of this, BauerBodoni is the superior typeface in my book.
