I had an '08 E93 M3 for 3 years... I now have an E92 M3. While I enjoyed the top-down experience, I knew that this time around I wanted the more hardcore M3. I loved the sound of the M3 with the top down, and cruising around was nice, but I can feel the weight difference significantly between the E92 & E93... both in acceleration and handling. Guess it all depends on what you prefer.
