Just like French (Parisian, Acadian, Quebecois, Creole, etc.), English has a lot of variants (British, Canadian, American, AAVE, Australian, etc.).

I would stick with poets that would be taught in high schools from the region whose English you learned. If you feel like you are still understanding the points they are trying to make, then I would branch out to other “Englishes”.

I am personally not a huge fan, but Robert Frost is probably a decent place to start.
