A lot of those are great! And yes, it sounds like a lot of variety until you look at how many more distinct accents the UK packs into an area a fraction of the size.

My own accent comes pretty much out of Seattle and it's always struck me as terribly boring and flat, very news anchor-y. I like the ones that have distinctiveness above all - British, American, or otherwise.

I grew up in Wisconsin and never heard bag-le. We say bay-gil. But the NW part of the state is a bit unique and basically MN.

I think I'd genuinely rather hear a southern drawl over a Wisconsin twang. Have you heard how they pronounce bagel? The worst!
