I usually default to sport mode, but honestly, it's a little hairy for something like the drive to school.
IIRC, the M button in my E63 M6 activated 2 addition cylinders for an extra 100hp over the norma, default 8-cyl mode. Beyond that, you could program the other settings such as traction control and transmission shift speed so the M button was a one-stop-shop for excitement  - again, a very noticable change in the car.
It seems the drive modes become more appreciable if the car has greater performance... there's a lot more bandwidth for change when you have, say, 500hp rather than what you can expect to change in a 150hp economy car. |
I use both eco and sport mode and prior to having those modes, I loved turning on and off the "over drive" mode depending on how I wanted to drive.
Certain vehicles I've been in also somehow feel like the suspension stiffens when put into sport mode. It's lively and aggressive. I love it!
Eco mode is mainly designed for those who evaluate their driving based on how low they can get their average L/100 km. Eco I guess is also useful for making your drive smooth and slow for the comfort of sleeping passengers.
