why don't all of you determine what airline or country you ultimately want to work for or in then contact the airline or some of the airlines in said country and ask them where they prefer their candidates train?
this may help you narrow your search
in canada the rumour is that if you are former military or have a university degree then you score more points with our national flag carrier Air Canada
you may also score more points if you went to an accredited aviation college
if the airlines you speak to don't care where you train then you'll have to find the cheapest option
