Spider is cheapest, Mojave and butter are priced about the same but I'd get a butter because I prefer the appearance of them and out of similar combos with butter and Mojave, the butter ones are usually better and super butters have less color than super Mojave which makes super butters more expensive. So, if you want a cheaper one I'd go spider, but if you'd rather have a (imo) a cooler looking snake with now genetic potential I'd get a lesser/butter.
