Just a couple of points
Vicar of Dibley, the Hawker 800 sim at Jerez is not just MCC only, it is used by MyTravel and BA for jet orientation and having completed the JOC at Jerez, MyTravel cadets have so far completed the A320 rating "without touching the sides" and have fared better in some cases than DEP's with considerably more experience.
Although it doesn't matter where you did your training in terms of getting a licence, you are likely to be viewed more favourably by an airline if you did your training somewhere other airlines have used. Not being snobbish - just basic psychology.
And also, Jerez is a great laugh it's got to be said.
