Methane is quickly becoming the new go-to fuel for new rockets. So why is it so popular? We’ll look at why more companies are using methane and oxygen, or methylox, fuels. Plus, which rocket using this new fuel will be the first to make orbit? Here’s the contenders.

Methane has higher ISP then kerosene, just compare Merlin vs Raptor.

Unacceptable.

Kind of a snipe quote though SoTOP. They do go on to state that the Staged Combustion engine(Raptor) would have the higher ISP regardless of the fuel when compared to the Gas Generator engine(Merlin-1D).

Race is between Relativity Terran 1 and SS.
Terran 1 isn't likely to make it to orbit on maiden flight, history isn't on their side. Neither is SS but given SpaceX's flight heritage probably has better chance even though its lot more complex.

I give each about a 50% chance of reaching orbit first try. Slightly more to Starship due to history of Falcon 9 and some of the initial flight tests with Starship (which all seemed to successfully complete ascent, in spite of problems… and especially for the higher altitude flights, ascent lasted a very long time, comparable almost to orbital flights).
