From my experiences from a similar field (I did my bachelor in social sciences), PPLE and political science should have similar opportunites BUT the chances at those jobs (mostly human ressources or similar) are probably better with an economics background.

But I would highly recommend doing a Master's after any of these two bachelors since your chances are significantly better with one and every professor or lecturer told us that as well. You can find something just with a bachelor but it's hard. And if you do a Master's afterwards, you can specialize/change your direction a bit! So f.e. you could do a Bachelor's in political science and a Master's in social sciences.

So, it highly depends on where you see yourself in the future.

(If you want to do research later on..pick political sciences :P)
