Hey guys i was wondering which PS3 console you think i should pick up, Slim or Super Slim?

I missed out on PS3 because i went with 360 back then, I want to pick one up for all the exclusives and games that just never made it to xbox, Ni No Kuni, Ico/Shadow of the Colossus, PS1/2 classics are a big thing for me too as well as the fact that I have a decent library of ps3 games claimed from PsPlus.

I've read reports that the super slim has frame rate issues and others say its fine, but it's also so much cheaper. Opinions and your experience with the systems would be greatly appreciated, I want to complete my Playstation collection with the right system :) Thanks a lot.
