YMMV, but both have been working well for me.
I have heard this "Better Shifts" between different ATF's. I guess it depends on what one person considers a good/better shift.
I know that a firm(er) shift is better for the tranny but, most folks like a smooth/seemless shift...I do too!
My '04 Altima(Matic-D) shifts just a bit differently betweent the OE fluid, the M1 and the Castrol IMV(IMV may have an edge in perceived shift quality).
The M1 seemed to be the best "all around" in terms of consistancy but, the tranny is getting older too! What I remember about the M1 is, consistancy:
* between shifts
* hot or cold outside temps
* smooth/crisp gear changes, up & down
* no shift flare...could be my tranny but, I did noticed something different in the tranny apon the addition of the Castrol IMV.
* no shift bump...hard to explain! I felt shift bump w/OE Matic-D
