as much as I like Road bikes, I also like fixies.
Id say go with a fixed-gear/singlespeed. easier maintenence/weight being the primary reasons i suggest fg/ss. And I echo what was said earlier: ANYTHING can get stolen. I mean, plus. You dont HAVE to throw on a pair of deep Vs, or matching saddles, or fancy your bike up just becasue its a fixed gear. You can just grab one that is really low-key and is very "quiet" looks-wise.
You dont seem to be getting either bike for show, so I guess personally, just a stock, low-key beater fg works fine. Being that yo are a student, youll always be on the move and cannot worry about maintnence. So go FG!
