Default CM or MRAD adjustment?

I'm thinking for a S&B scope with CCW, MSR reticle. However it comes as CM or MRAD adjustment. Which adjustment should I get? Thanks

In a nutshell:

1 mil = 10cm @ 100m

0.1 mil = 1cm @ 100m
(that's the beauty of a base 10 system)

So a scope with 0.1 MRAD clicks should be the same as a scope with 1cm click values, just marked differently. MRAD is a more modern standard whereas you'll find cm turrets were very common in Europe throughout the 80s and 90s.

As stated above,

100m * tan(1/1000)=0.1m=10cm

Users of the metric system would generally find MRADs/CM more intuitive.
Whereas, it seems that American shooters typically find MOA more intuitive since it is incidental that 1 MOA is very close to 1 inch at 100 yards.

Personally, I am happy to use either system as long as the turret adjustments match the reticle measurements.

The one thing that I'd never do would be to switch from CCW to CW since I'd find myself adjusting the turrets in the wrong direction.
