I have heard nothing but good things about both skis.
The chronic is a stiffer ski and will kill it on large jumps aswell as ripping all over the mountain.
The 2012 has recieved great reviews from a lot of people I know that has ridden them, very poppy and playful.
However the main difference between is that one is rockered (2012) and the other is not (chronic) and that might play a major part in your decision.
p.s. the durability issue with salomons is mainly with the suspect not the 2012
