I'm not sure about them doing any lockbar inserts on the 0560 (from what I know they haven't), but I will say my friend has the Reate Hills and the Horizon, and they're both excellent knives for the money.
The machining is very well-done, most likely on par with what you will get out of the 0560, and in my opinion the textre on the Horizon is better than the 0560. It is still grippy, but not rough at all, and is more consistant than the 0560 that I had. Not to mention it is all Ti instead of having a G10 handle scale. The action is in my opinion better, but I have only handled one 0560, and I have heard some mixed reviews on how they fire and how smooth the bearings are. I will say that the deployment itself is better than any 0560 I have ever seen. The detent is much better, and the action is faster and snappier without being to hard to deploy.
S35VN steel will not hold an edge as long as Elmax, but as Reate has it treated, it is very easy to sharpen quickly, and holds the edge for a good period of time, and the Elmax from ZT does occasionally still have some anomalies from what I can tell, though maybe not that most people will notice.
The biggest selling point for the Reate knives is that they are notably cheaper, have more Ti instead of G10, have a better action and detent in my opinion, and have a lockbar insert and steel that is easy to sharpen to increase the ease of use.
Essentially the only thing ZT has on them is that fact that ZT's warranty work will be easier, and you can get a Hinderer design in the 05XX group of knives. Honestly, the Horizon B with M390 steel blade and the 0562CF are going to be almost direct competitors, and once you get to that point, it's more of an opinion thing, but otherwise I would generally go with Reate over ZT these days.
