I personnally find the solid coloured ones ( yellows, orange, reds ) much more beautifull. Gardens tend to fade into greyish...
They are biters, nervous and mean ( imho ), but are awesome entry level snakes for one that is getting into arboreals.
Provide them with a tall terrarium, and platform perches. They do not perch on horizontal perches like ETB and GTP, nor do they coil.
