Integrated versus others, but not modular? I don't understand your terminology. There are two ways of obtaining an ATPL under JARs - integrated or modular courses. If you wish to compare UK integrated schools with other JAA integrated schools then say so. However, there aren't many outside UK that aren't associated with a national airline, and some will require you to do your learning in their national language.
Another consideration is that many UK airlines (including mine) insist on a UK-issued JAA ATPL. This is, at least in part, due to the ease with which licences and experience can be forged or fraudulently obtained in some countries. It's not difficult or expensive to convert, but it may introduce complications into your planning.
