The new WRX will have garbage reliability. Too many moving parts and a brand new platform. The 08 Accord will have its fair share of growing pains too, but this is what happens when you're a new model "early adopter".
The most solid car you mentioned is the Mazda 3 ... but if you're used to a V6, going to a small turbo 4 isn't quite the same.
It's hard to justify a $30,000 Honda. (first jackass to say, "Honda = Acura" is banned) It is what it is though, the top of its class.
