Well, at least you will still become acquainted with Oxford because Airways are moving there
In reality, the only way anyone will know aside from knowing the courses offered at the school is by the number of hours you have. You will probably end up with more having done a modular course. I'm guessing it will be a "structured modular", where you get a PPL straight away. With the integrated course you get no licence at all until you finish. The only other difference is more money to the CAA for the approval.
A rating is a rating and can be done anywhere once you have your licence. The licence gives you permission to hold ratings, and the ratings give you permission to fly.
