Integrated or modular... the only difference is that the first one is more expensive than the second, and you can manage your time and plan your study with a modular path.
In my opinion modular is the way to go: cheaper!
At the end you will have the same piece of paper that has an integrated guy.

Now, you have already got a PPL, why do it again? You can just convert it with two exams if you have more than 100 hours of flying time.
