oh Shannon - you don't make it easy
I really do love my marcis, my radix are wonderful, both my concinnus are really sweet snakes, that vagrans is a little slithering charmer, and you know how much I love Thing, my parietalis, as well as her beau. The other parietalis I used to have was a bit like a supersize cali with muscle though, so I don't know about parietalis in general.
My absolute favourite has got to be T.s.sirtalis. I love the variety, the size, and their disposition. I've yet to meet one with an unpleasant temperament, and they're certainly easy to feed. My Sammy once tried swallowing a shoe - really true - and there was no reason for her to be unreasonably hungry. No idea whether it was the leather or whether my friend had stepped on some food traces on the side-walk (pizza?)
