best general purpose STEEL shot-size for combo of big & small ducks?

[Macintosh]

Surprised I didnt find 7 different threads on the topic. For you guys who waterfowl hunt a lot, what is your favorite 12ga steel shot size for general purpose waterfowl use? This is mostly fairly open marsh, and a 50:50 mixture of small ducks (teal and wood ducks) and bigger ducks (mallards, blacks, etc) and only very rarely geese. While I'd like to think all shots will be close, cupped-wings, floating in the air as they commit to my decoys...the reality is some shots will be less than perfect like that. Not skybusting by any stretch, but with my decoy and calling skills resembling that of a chimpanzee, "getting them close and shooting them in the face" is perhaps more aspiration than reality.... Are steel 2's too big for the small ducks? Are steel 4's too small for the big ducks? Are 3's the perfect answer? Does it actually matter?
Any experience, advice or snide remarks are welcomed. Thanks in advance.

I shoot a mix of 2 3 and 4's in both 12 and 20 and can't figure out what works best or what I like. So im curious too.

Up close in the dekes, #4, out further or possibility of geese, #2, that’s my preference

Pretty much the same here, sometimes use #3s for ducks too.

1's and 2's for further pass shooting and 3's for up close decoying is my preference.

I like 4's for decoying ducks and 2's if there may be geese or longer shots.

2’s for ducks. BB’s for geese.

2 or 3 for standard steel shot. Don't over think it.
