Kiteman, These were two of the schools I considered. What I will say is don't go somewhere just because they are doing you a "special offer" DL is hard - very hard - I've now only got 5 exams left to go, so have a good idea of the amount of time you need to put in.
On top of that, you need to make sure that the support you need is there when you need it, and the training material is top quality. The other big factor (if you have a job to do as well) is hoe the groundschools / brush-ups work. It is all time of work, and you need to work out which method is best for you.
Most of all, try and speak to some people who've been to both (you can always turn up at the school and speak to students) and see what they think.
With ATPL theory by DL, the course price isn't the headline - you will spend £800 on exams if you pass first time. You need to work out the adittional cost of resits and extra training if you don't get the quality materials & support you need.
