I prefer to strike a balance or have a combination of traditional design with old choices. Needless to say it feels so amazing to have the experience both worlds. It's a great move to have those hard to find pets because it gives a sense of accomplishment.
I love to have rare pets. They always have that special appeal aesthetically. And some rare pets always have special abilities beyond the regular pets in a virtual pet game. It is another level of fun raising a rare pet on a virtual pet game.
