The CDS comes with an MOA turret that is not one rotatation limited, therefore it will operate to the mechnical limits of the scope - just like an M1.
The CDS and M1 turret will do the same things on similar scopes.
The CDS has a zero stop feature.
The CDS turret is lower profile than the M1.
The M1 does have the "cool look" factor.
I have used both turrets.
Some say the CDS turret can "unknowningly" spin out of adjustment in scabboards and such - I have never encountered this problem.
On a hunting rifle I prefer the CDS due to the lower profile and zero stop. On a long range or similiar rig I prefer the M1 or Target turrets.
YMMV
All good points but I would not reccomend using a CDS without a zero stop on could lose his zero if not careful!
