First, I would handle, examine, and operate the knife to see how it feels and fits in your hand. Then consider the purposes or plans you have to use it. That should help to narrow your choices.
For my purposes, I like assisted opening knives and the two that fit my needs and hand are the BM Stryker 913 and Barrage 580. The Stryker offers a choice of blade type, (Tanto or Spearpoint), size of blade, and choice of edge and blade coating, G10 scales handle material and Axis lock. The Barrage offers similar choices, liner lock, faster assisted opening, a molded handle but a drop point blade. I ended up buying both.
Others I considered but rejected were the Presidio 522, Kulgera 930, Ares 732, Axis 805, and McHenry-Williams 710, either because of blade type, handle material, fit and feel, or were not assisted opening.
Hope that helps.
