The big schools are very very much of a muchness. The syllabuses and equipment are virtually interchangeable. Their home airfields each have their strengths and weaknesses and their staff have as often as not worked in the other camps at different times. They are all audited by the CAA to attain the same standard.
The only thing I can promise you is that if you ever breath the notion in public, that you are somehow a better pilot or more employable, because you trained at School X - then you will be identifying yourself as a total prat to the person you are trying to impress or persuade.
It probably is easier in the bigger full time schools. The reason being mostly to do with the fact that your train with a bunch of coursemates from start to finish.
This helps your morale, you learn from one anothers mistakes, you are spured on by competition and cheered up by the comaraderie.
You get the same on the Modular route but the people on your Groundschool course are probably going to be different to those on your Commercial flying course who in turn won't be the people you did your PPL flying with. So its a bit more diluted and fragmented.
That said I have seen Integrated courses where people fell out with each other and bitchy cliques developed - much to the detriment of everybodys enjoyment and performance. So sometimes you can't win.
Me - I'd go Modular, pocket the saving and try not to think too hard about those lying around the Pool in Jerez with their coursemates most evenings soaking up that lingering Andalucian sunshine.
Squak2002 - ask some searching questions about weather in Jerez. There are some interesting summer day winds, the Lavanter, Winter fogs, Summer heat bans and all manner of other weather and airspace issues. Its probably no worse than the UK but nor is it significantly better. Make sure you understand what will happen if your course is delayed due to weather - who will pick up the extra accomodation fees etc. They have always done right by courses caught out in the past with unflyable weather. Make sure you know the score for the future if you decide to sign up down there.
The best flying instructors I know of in Commercial Flying Training all currently work in small FTO's. There is some good training to be found in tatty buildings on small airfields. You just need to look hard and gather a lot of opinion.
Good luck,
