If you are going to use the reticle for hold over reference points, the TMR is the best by a large margin simply because it offers all the advantages of the Mil Dot system but wuth the added advantages of no dots to cover up alot of the target, plus, it has the 1/2 mil hash marks as well.
Basically there are 1.8 moa between each hash on the TMR instead of the 3.6 moa for the conventional mil dot. Much less guessing involved when your using the reticle for reference hold points at long range.
If you are dialing up for the each long range shot, I recommend the Plex or as it is the simplest and least cluttered. If your dialing up for the shot, no need for the other reference points unless you want some windage reference points but usually those that dial up for each shot also dial in the windage as well.
The scope is a very quality scope by the way, good choice.
