It makes no difference at all to the small piece of paper that you receive at the end. A licence is a licence. Needless to say the bigger and more expensive schools will tell you otherwise, but then what would be the point in them employing so many people in their sales department if they didn't tell you that? 10k is a lot of money. Say you had 10k to spare, that means you could add an instructor rating as well and try and get an instructor job if all else fails. Ultimately no right or wrong decision. Look into all options and choose the route that suits you the best. Oh, last point...please don't listen to the people who say you'll get a shock flying in UK airspace if you do your training elsewhere(it's all the same).
