I can think of two advantages of doing the ATPL exams. The first is the obvious one - the opportunity of going on to do the IR within 3 years of completing the exams, if there's even a hint of a chance you may decide to do this. The other advantage is that you have a far wider range of schools to choose between for the ATPL exams.
I would guess that both of these arguments are pretty weak for someone in your position, and that the CPL exams would be more appropriate, but it's up to you to decide.
