Sorry it won't help your choice but remember there are many more than 2 UK-based schools. Look in the back of Pilot, Flyer of Flight International, and on the adverts here on PPRuNe. It is worth taking a little time to investigate, as you will spend £40,000 - £65,000 on this!
I am not abe to comment in quality, as my school went bust and I now work for one of the FTOs. I would agree with everything FFF says.
