The Raptor burns methalox, first flew in April 2023 and is in mass production with V3 entering production. Current production rate is 500 a year but will need to ramp up to 4000 a year with current Booster/Starship production plans.
Blue Origins BE-4 first flew in January 2024 with a current production rate of 42 a year.
If you want to go back and argue who flew the first methalox engine to put a payload in orbit - it was the Chinese.
