I thought you were talking about Fibre To The Premises for a second and was going to fight you.
My take, for what it's worth, is that we don't even have FPTP in the UK, we have Winner Takes All, since they don't even need to get 50% to win, they just need to be the most popular which could mean 21% of votes with four similarly-popular opponents.
WTA/FPTP asks the question "who is the most popular?"; AV asks "who can the voters agree to compromise on?"; STV asks "who best represents the voters?"
