I started with Invictus, then tried Taccom and finally switched to Safariland. The Safariland's work best for me. They have excellent retention, even if you have to go prone on them, but they come out easily when you want them to. The spacing between the quads is better for me as well, the Invictus were a little too close together for me to quickly grab 4. I found the Taccom caddies would leave shells on the ground if I had to go prone. This is one of those Ford, Chevy or Dodge is better kind of things though....everybody thinks what they use is best.
