Sorry EGDR, didn't mean to scare you. You will come out with the same licence if you go with Multiflight as you would if you went with OATS.
As to what future employers think, I don't think there's much doubt that an airline would rather hire a 200 hour pilot from an integrated course than from a modular course, but for the best part of £20,000, you could get yourself a Flight Instructor rating and afford to live on an FI's pay for a year - by which point you would probably be looked on more favourably than students of integrated courses.
