I have the Locking Turrets and the More Tactile Clicks. The LT model is easier, MUCH easier, to use. The Double Turn process is a bit more involved and if you do a search, you will find a lot more questions regarding how to zero the DT turrets than the LT turrets. Also, I leave the windage knob locked since the turret can get turned when I take it in and out of my Eberlestock pack. Best to know that the windage know will NOT move, period. (It happened to a friend of mine).
The MTC is personal preference, but I enjoy it. The knob clicks get worn in the more you use it and as such, the MTC is less noticeable and is very helpful when I am in a hurry. Every tactile click indicates to me 1 full MilliRadian. Easy and simple.
As for the MSR reticle, I love it. A few competitors are going the H2CRM route because of the wind holds, but I disagree and again, this is a personal choice.
