Need to replace the OE Dunlops at 15k miles on a ML-350 Blue Tec...any suggestions on which would be the best choice of the above mentioned options?

I've got a 15 ML 350 Gas with OE Dunlops w/ 43000 mi on them. Still have almost 4/32 of tread left. 36 PSI all around, rotate every 10K mi.

Had the Alenza in my old Acura MDX. I would say 8 out of 10. Good handling in wet condition and noise control.

I have had Michlin premier on 2 ML 350's and i am very happy with them
