Cloud is ongoing expense
I'm using CS6 Master Collection and have been since sometime in 2012; I didn't really need to upgrade to CS6. I could still be using CS5 (2010) and be happy, and I skipped CS5.5.
I receive an educator/student discount on Adobe products and you will be able to as well.
Compare $15.99 a month to rent Creative Cloud v. price of ownership of whichever Adobe programs you need. There are various suites smaller than Cloud and Master Collection. I use Master because: video, web, photo, animation.
Creative Cloud will always be the latest version, but I haven't paid anything since 2012, I own CS6 and don't plan to pay anything for a while - and my cost of CS6 was an upgrade price.
I'd be happy owning CS5 right now if I didn't want a couple of features in one program and, if so, I wouldn't have paid a penny since 2010.
