Why are SpaceX Raptor engines the best Rocket engines ever made?

Elon Musk has a goal to establish an operational cargo and crew architecture for missions between Earth and Mars, and possibly beyond.
Achieving this ambitious goal requires a massive launch vehicle with a cluster of high-powered engines, a propulsion system for operation in deep space and a propulsive landing and ascent architecture for operation in the Martian atmosphere. All this will be realized by SpaceX’s Raptor engine family.

Let’s compare SpaceX’s open cycle Merlin engine that powers their Falcon 9 and Falcon Heavy rockets, NPO Energomesh’s oxygen-rich closed cycle RD-180 that we see power the Atlas V rocket and Rocketdyne’s open cycle F-1 engine that powered the Saturn V all run on RP-1. Then we have SpaceX’s full flow staged combustion cycle Raptor engine that will power their Starship and Super Heavy booster, Blue Origin’s closed cycle oxygen rich methane powered BE-4 engine that will power their New Glenn rocket, ULA’s upcoming Vulcan rocket, and Aerojet Rocketdyne’s closed cycle fuel rich RS-25 engine that powered the space shuttle and will power the upcoming SLS rocket which runs on Hydrogen.
Since all these engines run at sea level, so first up, let’s take a look at their total thrust output at sea level, that’s a fair place to compare them. For further amusement, Let’s go from the least amount of thrust to the most. The Merlin produces 914 kN of thrust, the Raptor currently is at 2,200 kN, the RS-25 produces 2,280 kN, the BE-4 hits 2,400 kN full power, the RD-180 is at 4,150 kN and the F-1 is still the king out of these at 7,740 kN.

Now one of the factors that affect both thrust and specific impulse is chamber pressure. Generally, the higher the chamber pressure, the more thrust and potentially more efficiency the engine can gain. Higher chamber pressures let an engine be smaller for a given thrust level, also improving their thrust to weight ratio. The baby here is actually the F-1 which only had 70 bar in its chamber pressure. Next up is the Merlin engine at 97 bar, then the BE-4 will be around 134 bar, then the RS-25 which is 206 bar, then the RD-180 which has been considered the king of operational engines at 267 bar, that is until the Raptor is now appeared which is the new king of chamber pressure at 330 bar!!!
