Being from Seattle, I don't have the habit of saying "y'all" but I recognize its utility. I like it much more than "you guys." I guess the Northeast equivalent would be "you's."

The worst thing ever is the second-person plural possessive that you hear on the West Coast: "you guys's." The correct word is just your but in the process of searching in vain for an unambiguous plural version we've created a monstrosity.

I'm from Pennsylvania; the alternatives there are "youse" and "yinz" which are two of the most awful words in english. (Both mean "y'all.")

"Yinz" is the north Appalachian version of "you'uns" or "youns" in central/south Appalachian. So not totally awful in context.

"Hey all" works too! I probably use "you all"/y'all/guys about evenly

Once you mix something else in and stop saying 'guys' practically every time, it's hard to go back.
