OK --MY FLAME SUIT IS ON!! This is the truth of the matter but it depends on the rifle and the shooter. Most people do not have the skills nor the rifle and or ammunition that will fully realize the advantage to having a .2 MOA adjustment.
If you do have the ability to take advantage of this then by all means it is a good thing!
Between the 2 I like 1/4 MOA for a long range hunting scope, the best IMHO is 1/10 of a Mill. ( 1 CM) This gets you to distnace quickly.
Example at sea level with my 338 Lapua I can get to 1,000 yards with 6.9 Mills sighted in 2" high at 100 yards.
Useing MOA it takes 23.75 my S&B PM11 has 14 Mills per revolution and that gets you a lot of distance.
IMHO a laser is for ranging. I can also tell from your post that you have never used a scope that adjust in CM (1/10 of a Mill). I thought as you do untill I used one.
Why do you feel the need to turn Mills into MOA? All one needs to do is to set your ballistics targeting software to print out your drops correction in centimeters (1/10 of a mill). you only need to know how many adjustments that you need, not how many MOA's, unless your scope adjusts in MOA.
I own 5 Nightforce NXS scopes that adjust in MOA and 2 S&B scopes that adjust in mills and I like the Mills better.
It's true I've never used MILs. My conversion to MOA was for comparison of resolution described.
I agree completely about laser ranging. So I see no need for FFP scopes, MILs on reticles, nor MILs in adjustment.
Ideal IMO is SFP scopes, medium-fine crosshairs, and IPHY across the board.
That just seems simple to me.
But I'll use what I can get...
It really matters not how a scope adjusts as far as getting on target, as long as you know which one your scope adjusts in you are good to go IMHO . A mill or MOA or IPHY yards reticule is use full for drop correction if time is of the essence IMHO, but certainly not a necessity.
