I can only comment on personal experience and do not want to advertise.
Having been a Modular JAR student at London Guildhall (now London Met Uni) I completed my CPL-ME-IR at Stapleford. Not the full new system but the seperate CPL, ME, IR. The training was more than good and with on airfield accomodation there were no problems.
Training at Stapleford was in 2002.
There were students who didn't like Stapleford (Set-up / Instructor etc etc) and some finished at other schools. However these did seem to be the ones who struggled / required further training. It is a difficult and stressfull course but hey, You KNOW that.
Best luck to all.
