As above, noone can give you this answer, as noone will have been to all of the schools.
Some people will rave about the school they went to, others will come out with some crazy horror story which could of been a one off and mostly their fault.
The schools wouldn't stay in business if they were all terrible, so I'd hope most modular schools are of a similar standard.
Visit them yourself and do your own research before you part with such a significant amount of money. Free advice on an anonymous internet forum isn't the best source of info, as you will have flying school owners posting on here with testimonials about how good the training was.
