The biggest plus point from a consumer's point of view is that you can mix and match training providers. You can then optimise your own training on cost and specialist expertise criteria.
I did my PPL in at a now defunct US FTO, my ground school with Bristol, my MEP with NAC, and the rest with EPTA in Bournemouth.
I was asked about my training in my job interview (which I passed incidentally), but simply to help them build a picture of me. I really don't think they gave two hoots where I actually did my Ratings, as long as they were valid.
