I feed frozen mostly for the convenience. 5 snakes would be a lot to try and live feed, and wouldnt be cost effIcient unless I was breeding my own, which is way more work than it is worth for me right now. I do also think there is something to be said for the humane euthanasia of your feeder rodents. Even tho they are bred to be eaten I do think they deserve a peaceful death.
Didn't vote since there was no choice for both. I breed and sometimes even freeze my own rats, and buy all my mice frozen. I feed whatever work with each snake and is most convenient for me. I have enough that won't consistently take frozen that live is easier most of the time, but frozen is less work.
Most of my snakes eat frozen thawed or prekilled. I do have a couple that are stuck on live for the time being.
