Dark horse vs m4 comp xdrive

Which one is more worth it to get?

I know some say the dark horse is a dud and not very modifiable yet. Plus I hear that it’s slower than the S550 and weights too much.

The m4 has far better build quality and modifiability. I’ve heard of a simple tune reaching crazy numbers.

However which one is more fun as an entire package? I realize the dark horse has a manual which is what I’d get if I went DH. The xdrive has the ability to do AWD too. Just wanted some thoughts.
