The two are not a straight swap though are they.
Integrated is more expensive and will require 100% dedication, it cannot be done alongside work etc.
Modular is cheaper and more flexible, but weather we like it or not, less favoured by the airlines.
It has been covered so extensively on pprune i could write a paper on it.
If you have the money, and few commitments, then Integrated all the way, wish I could.
Best of luck (with the flying and future search efforts)
