PS3 Slim vs PS3 Super Slim

All welcome. Guys please tell me: decided to buy a ps3 (ps4 budget crunch), but don't know which version to choose PS3 Slim or Super Slim. In terms of design love Slim, but I read reviews say that it overheats often than Super Slim. For the price difference is not large, and quite pleasing to the possibility of firmware Slim version. Would like to know will there be any problems with the iron, or forget about the design, the firmware and not bother with the fact that the possible overheating and problems. Thank you in advance.
