When considering any flying school, one should look at the instructor ranks and the experience of the line instructors and the CFI. Whilst it is likely that you will fly with junior instructors, you should insist on having one instructor at least until you go solo. If they chop and change on you, that is not good and more than enough reason to look elsewhere. If you think you are getting screwed about then insist that you fly with a senior instructor. Stick with the same one and considering canceling a lesson if your usual instructor is not available. As a general rule the quality of instruction is not as good as it was 15+ years ago, so it is all the more important that you assess the quality of the product from whatever school/s you are looking at, and you can usually only do that by asking about.
If you believe you are not getting the best possible training then front the CFI and if he/she does not fix it, then go elsewhere.
I have no experience with the two schools mentioned, but a lot of experience in days gone by at EN. Yes, it is a good place to learn, but times have changed and you may well find that it is not good bang for the buck unless you receive good high quality instruction.
I agree with the comments that country flying schools are usually the best value, even if you have to take a few weeks off and do it full time.
Good luck
