Initial impressions:
Great size and ergos. It's a little more compact than either and different enough from the Servo that I'm glad I have both. The grip is VERY similar to the Myna, just a bit shorter / smaller, and it's a grip style that I really love.
Action: This is a brand new knife, so I would assume things will change a bit as I work it in. Flipping deployment is very solid and pretty comparable with the others. Does not drop like a guillotine like the Servo on closing. I don't consider that better or worse, just different. They're all very smooth, with the Servo being more like ice and the Myna / Hyrax being more hydraulic and glassy.
One difference - I feel like you have to close further on the Hyrax to overcome the detent than the others. Starting out, I found myself doing the flipper double-clutch with it quite a bit, which doesn't happen at all with the other two. I adjusted pretty quickly, but it does feel differently to me in that regard, and I would give an edge to the Myna and Servo for closing.
All 3 are perfectly centered (I have 2 Mynas and both are), and there is zero blade play in any direction. All 3 knives feel superbly constructed and solid.
My personal favorite is still the Myna, but all 3 of these are going on heavy rotation.
