Kind of a late reply, but I went with the Tremor3 in a Steiner M7XI and have run a couple of matches with it. My first match with it had 30mph crosswinds, and those [2, 4, 6] numbers really threw me off when trying to hold more than a mil of wind. I ended up not dialing at all for the rest of the match and using the wind dots, which worked surprisingly well, as I had never utilized the tree function of the reticle before. From then on, I've really only used the reticle instead of dialing anything at all.
Everyone talks about the Tremor3 being busy, but I don't think enough people talk about how thin the .2 marks are. Compared with the JVCR on my USO FDN at 12x:

Recommend zooming in on those reticles and you'll see what I mean.
I know OP has already made his choice, but just in case anyone ends up on this thread with OP's same question, I figured it's worth dropping my experience here.
If you like to dial elevation and hold wind, Tremor3 loses for me. All the .2 marks are the same, and very hard to see. I've had a hard time picking out .6 from .8 on other reticles (hence I got the JVCR on my other scope). If Horus changed it to have .2 graduation marks in the wave format of the JVCR, PR2, or Mil-XT, and dropped the mover numbers up top in favor of plain mil marks, it would be a winner for me on all counts.
If, on COFs with troop lines, you like to dial the nearest one and hold the rest, Mil-XT wins, because wind dots don't translate, and the christmas tree goes out to 3 mils on that first mil line.
If you dial elevation
and windage, they tie.
If you don't touch the elevation turret and just leave it at zero, Tremor3 wins for me.
