G sxty is spot on. It doesn't really matter. Despite what people say. There is sometimes the impression given the OAA or FTE are the Oxbridge or Harvard of the flying game. They're not. They are good and you will be a well trained pilot at the end and indeed you may be offered an interview on the basis of having been trained there. Assuming you maintain a high standard during the course. You won't be put forward if you were one of their 'remedial' students. In another thread recently dealing BA, several victims of marketing hype were of the belief that pilots coming down the modular route were some kind of second raters. Which is ironic considering OAA has a modular course.
It really depends on how much money you're willing to spend or more likely have to spend. Given the tendency for airlines to demand up front payment for type ratings these days. You might be better hanging on to some of your hard earned against that possibility. It's up to you though.
