Ok, I guess as this is my job I can try top help a bit there :)
So, 1st of all, what's probably the most important thing was correctly told by David, regarding taxes you'll be able to get the same % of deduction. Limit for 3rd pillar is 6'566 chf this year for 3a (prévoyance liée) , and as you've a C permit so fill a tax declaration you can also deduct 3b (prévoyance libre), max amount depending on your familly status, but minimum 2'200chf/year.
You can probably deduct a bit more in your second pillar, depending on your age, when you start working, your income, etc.
Now, for what's the most interresting, I unfortunately can't give you a clear answer if it's one option or the other. The reason is it's based on too many individual factors (like the ones I mentionned earlier, if you own a house or not, if and when you might leave switzerland, etc) and also the quality of your 3rd and 2nd pillars.
However, if you need more accurate answers you can contact me by sending me a private message there.
