Some scopes have more MOA or MIL per revolution but use coarser intervals, say 15MOA with 1/4 MOA clicks vs 24MOA per revolution but with 1/2 MOA clicks. In that case, speed goes to the 24MOA turret, while fine tuned adjustment goes to the "slower" turret. Which is better will depend on the size of the target you need/want to hit at long distance. If you are trying to hit a 1MOA target at 1000 yards, the 1/2 MOA click becomes challenging, since your dope for that distance might actually fall between your clicks, and that is an interval of slightly more than 5 inches, or half the size of the target, whichever way you want to think of it. For larger targets, it won't be as much of a handicap. On the other hand, the turret with 1/4 MOA clicks will need more turns to get on dope, but will have a finer solution on target. You can hold slightly high or low with a graduated reticle, of course, but hold-overs at long range are generally the less preferred method for making good shots. Read the review article on Huskemaw scopes on this site, and you will find a discussion of turret click value pros and cons that explains the argument very well.
