Which group of people are nicer in real life?

Unitedstatesians >>>

Never met an englisian person so IDK

Probably USians. The English are more reserved and unwilling to be overly familiar with strangers.

Both can be very rude or very polite, not sure on the whole though

Americans are far more polite. Us Brits are notoriously cold and grumpy, and that's the way I like it

Southern and Midwest Americans >>

Although when I went to Europe last summer i was pleasantly surprised by how helpful and nice the English were, its the Parisians who are downright rude and snobbish.

English people are rude but say sorry after every sentence, so idk.
