Everyone is saying the facelift E-class has much improved interior quality over the pre-face lift version, but i disagree. I have spent considerable amount of time in both version and i can honestly say they are the same, the E class interior has always been great.
Back to topic. IMO, it is Mercedes vs Audi. Never really liked the BMW interiors, i like the 5 and the 6, and X5, but the rest is just not very good.
Right now Audi is winning my vote, only just because of the R8 and A5 interiors. Mercedes is quickly catching up with the new S and the CL. I will wait til they have completely replaced their older passanger cars before making a final decision. I will give MB a chance to prove themselves.
