If you use it without the strong drawl it’ll blend in perfectly fine. I’m willing to bet that the reason you don’t think it’s sounds nice is cause your brain hears the world then your brain hears in Squidbillies rather than just another Americanism of dropping syllables. That internal shift in your brain can cause dissonance and make it sound ugly.

I’ve worked hard to get rid of my southern accent but to me, “you all” just feels forced and clunky. Kind of like when someone uses an unnecessary vocabulary word when it doesn’t add any extra meaning.

There are many different accents for the word. My second favorite is the Georgia Peach / Antebellum. I don’t know the term for my top favorite but I’ll dub it “the highly educated and eloquent college professor who grew up in a swamp”, it’s like brown sugar for my ears
