I don't have any personal experience with either (other than seeing them at shows or whatnot) but I have two different friends who both have (or have had) a rosy....and both snakes were "mean" as heck. LOL I don't really think snakes are ever "mean"...but they certainly weren't docile and did not like to be handled at all. Now, I don't know if my limited anecdotal experience with them means I just got unlucky to find the only two non-docile ones around...but I do think that docility (is that a word? LOL) isn't a "given."

As to which to choose....I don't think I could pick. They're both very cool in their own ways. Maybe get one now...and plan on getting the other "someday."
