FPTP doesn't work well at all for presidential elections. FPTP is infamously why George W. Bush became president.

Al Gore won the popular vote in the 2000 presidentials, which in a true FPTP, would have netted him the POTUS.

Trump also lost the popular vote, but Clinton got really screwed by the Electoral College. Would life (in the US) have been better if Al Gore and Hillary Clinton had been made presidents instead of Bush and Trump (notably two of the worst presidents)?

Maybe. But the fact is that under a purely FPTP presidentials, Bush would not have won.
