To be fair, most engines that NASA uses are much better than the Merlin engine. Merlins are based off of engine designs from the '50s. Raptor on the other hand is one of the most advanced rocket engines ever developed.

SpaceX Merlin architecture is simpler than staged combustion (eg SSME or RD), but it has world record for thrust/weight & thrust/cost engine. Raptor has better Isp, but I’m worried it may fall short on those two critical metrics.
