We have a mixed bunch here too - through the winter, most of our girls were laying every other day.
Now the weather is warming up, they are pretty much laying every day, without exception.
We have 2 ISA hens, 3 Maran hens, a Green-legged Partridge hen (lovely almond-white eggs) 2 blackrocks just started to lay, & 3 white sussex also just started to lay.
We also have 6 point of lays who have all just started & they are a mix of the above with a Rhode Island Red rooster - and are pretty much laying every other day.
I have to say though, that for consistency, it's our ducks that win! Out of 4 ducks & 3 muscovy ducks, we get 6 eggs each & every day without fail - sometimes the full 7!
I think if you choose good healthy birds and keep them well, they'll perform for you, but if you don't want to have any that go broody, then stick to the favourite ISA's, or the leghorns - avoid Marans!
I'm hoping that at least one of the marans will turn broody soon - but instead, it's our largest muscovy duck that has caught the motherhood bug first... so I caught her today beating up on the young duckling & anything else that dared go near the chookhouse, and a little later I caught her trying to roll a duck egg out of another nest box to steal it for her pile!
She is now firmly esconced in our large broody box with 15 duck eggs & very happy she is too!
Good luck with it, I'm sure whatever you choose will do just fine once they have settled
