I would say CV if you don't want routine, CX if you want routine and no fun at all.
Moneywise it's strongly depending on the US$ and where you're living as the HK$ is still somehow linked to the US one.
I don't see 20 years for the upgrade in CV but if that's your primary factor, stay away better opportunities out there those days, not in central Europe though!!! Unless you're 25 and qualified.
Good luck.
