I think it depends a bit of the indiviudal snake - though some species are quite active. I find that spotted pythons are childreni are the most inactive, and the most active snakes I own at my murray darlings, and my coastals. My womas are lazy slugs!
I have found that by far the most active snakes I've seen in reptile parks and zoos are definTely inland taipans lol but I wouldn't recommend getting one
