It will be easier to get a job in almost any sector with a degree from Trinity rather than a degree from Galway (particularly outside Ireland), you will probably meet more interesting/driven people there, and you can try to make your PPES degree more quantitative if you want through particular choices (eg the econometrics option in third year economics or quantitative methods in fourth year economics), although it is certainly too early to be making specific choices about modules at this stage!
As others have said, it will also keep your options broader, which is valuable for all of us but particularly those of us who are still trying to work out what we are particularly good at.
Strongly urge Trinity.
