You change languages, currency, you need new bank accounts, new health insurance, completely different educational system. All administrations are different. The culture is also a shock. You will never find any of the grocery or shop you used to buy.
A French going to the UK is not much different than a Mexican going to the USA.
The only advantage is that you don't risk being deported by the police if they don't like you papers. You are effectively allowed to be there by the virtue of being European.
What's it with the bank accounts? You can transfer money within the EU without any problems. I pay my rent in Spain from a German bank account. Though, getting wired internet is another thing, these companies seem to ignore European law.
That's a huge advantage tho, especially if you don't already have a job offer at hand. In fact if you're not in a well paid/in-demand profession like software dev it is almost impossible to immigrate legally from outside the EU.
