Dual citizen - which passport to use for multi country trip?

Hi, Just became a dual citizen and a bit confused with the passport situation. I am currently travelling in China and will be flying to South Korea before heading back home to the UK. (I'm both a French and British citizen) I used my French passport to enter China, as it didn't require a tourist visa. If I use my French passport to fly to Korea, should I use my British passport when checking in to go back to the UK? (Don't think it will work with my french passport as they'll ask for an ETA). I'll have to make sure to show the same passport at border control in Korea for the stamp. But will they not be confused about flying in and out with different passport?
