There’s definitely rockets that have had over a 1.5 : 1 TWR. It’s extra advantageous for Starship because it minimizes fuel usage, which for a fully reusable rocket, is one of the biggest expenses!

More accurate word is “propellant”, rather than “fuel”. Starship is ~78% liquid oxygen, ~22% fuel.
Propellant cost is of primary importance for a fully reusable rocket, so reusable rockets want high thrust, as thrust below T/W of 1 is irrelevant.
