A lot of question marks in your previous post. Have you done any assesments for either company? I know lot´s of (very capable) people who have tried the CX interview and failed to get the job.
For as far as your initial question goes: it´s really a no-brainer.
CX
is a career airline, whereas EZY is a nice steppingstone to get a lot of jet hours very quickly so you can
join a career airline.
If you´re willing to move to Hong Kong (I assume you are, otherwise you wouldn´t consider it) then go for CX!
