I have 48 ducks in a a good amount of breeds. Ironically, I don't have a lot of the ones you are considering. The breeds I have are for show, except for my Penciled Indian Runners. I got them first and couldn't find them from a show breeder. I will say they are significantly more friendly than most my other breeds, but they are also the only ones I've raised from 2 days old. They are our favorite ducks partly because they are so friendly, but they are hysterically funny, more so than any of our other ducks.
Our second favorite, which we really were not in love with when we got them is our while Call Ducks. They are show ducks and the breeder wasn't spending any time with them, so they came very wild. But in the last 8 months the white ones have gotten so friendly, I've changed my mind about them. And as you can see from my Avatar photo, I like GIANT dogs, so these tiny ducks had to earn my affection LOL
Our Pekins are for show, or I'd never have them. I really discourage people wanting pets from getting Pekins. My two Pekins eat MORE than my 10 Indian Runner ducks! It's really a shock when you are used to ducks that give eggs and don't eat so much LOL
Our other ducks are: East Indies, Australian Spotted, Snowy Mallards, White Indian Runners, Cayugas, and some other varieties of Call Ducks.
Of all these, for eggs, I'd pick the Indian Runners first, but I'd look for people breeding for egg production and I'd select my ones to breed from my highest egg layers. They have the lowest feed cost and for the money lay a lot of eggs. Second best for eggs, and a very nice calm duck (quiet too, at least compared to my other breeds LOL) is the Cayugas. My Cayugas might eat a bit more than the Indian Runners, but they are no trouble, and they are stunningly beautiful, at least in the show quality ducks. The Indian Runners do lay more days a year and Indian Runners seem to be the most interested in constantly foraging. None will survive well free ranging because predators are much faster than domestic ducks, but we use movable walk in pens and move them daily. We keep the pens in wide open areas that tend to discourage predators and move them daily. I can't imagine the nightmare of keeping them constantly in a pen.
