What does "the best part is no part" mean?

“We’re going to try to catch the Super Heavy Booster with the launch tower arm, using the grid fins to take the load. Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount — ready to refly in under an hour. Legs would certainly work, but best part is no part, best step is no step.”
