I would say either, but in both instances, there are more than one. There are at least a half-dozen American accents, and there are dozens of accents in England alone (not including the three distinct accents in Wales, the nine or so in Scotland, or the accent predominant in Northern Ireland). In just the county of Yorkshire alone, there are 3 different accents, and in Greater London, there are several accents that are broadly distinct from one another.

Both: I'm from the US. My mother is from England. I grew with both and enjoy all accents! It's helped me to be great at teaching pronunciation and learning Spanish and Japanese pronunciation.

English! I find their accent adorable!

What about the Aussie accent?
