These are very similar typefaces. I say the century-old standard, Cloister Old Style, probably remains the better for lengthy text. Adobe Jenson may be prettier, but it has more of what I call a strobing effect, like stripes on television.

(Centaur is prettier still, and not very strobey, but emphasizes a modern elegance over historical authenticity, and so perhaps ought to be grouped separately.)
