If it's purely down to completion times, from my experience, a modular course takes less than a year, while my understanding is integrated courses last anything between 14 months to three years.
So there you go, while you play it safe by, hopefully, keeping your job and steadying your finances, you can still study for your theory exams and hour build as the situation permits.
I for one cannot see a fault in your decision, if that's what you were asking.
