M3W vs 4/4?
Having had both I can assure you that they are very different experiences!
THe M3W is a great car and very exciting to drive.
The 4/4 is a great car - with many more comforts than a 3W. Possibly more comfort over a long drive or touring.
But try not to compare too much as they are fundamentally different.
It really comes down to which of the two "experiences" floats your boat more!
