I have both and would have a hard time deciding which I would want, between the two, if I could only have one.
They have the same care requirements (though Cresties tend to like insects more than the Gargs do), both have about the same amount of tolerance to being handled, and both are "cuter than a button".
That said, I suppose that if I *had* to pick, I would say that the Cresties edge ahead of Gargs, by only a wee bit, with re. to tolerance of being handled.
A little more info...
Cresties have more "sticking" ability, and feel a bit more "velvety", than Gargs.
Cresties jump (leap) more than Gargs do.
Gargs can regenerate a new tail while Cresties cannot.
Whichever you decide on, you cannot go wrong (in selection) with either one. Both are great.
