I think the Dooney has a lot going on. I like the Florentine style and python, but together, it's a lot. The black is a big simpler and of the two, I'd choose that. Granted, simple is more my style so you should take that into account.
Same response as on the other thread------- that red zipper and those green backed tassels just ruin the look of that Dooney. While they may be ok for a solid colored leather bag IMO they clash horribly with the snakeskin print.
