Whats difference between zremesher and qremesher? In my video tutorial is show qremesher, which i can’t find in my zbrush. In place of it is there zremesher. But i don’t have the CStiffness option. 
Zremesher is an improved version of Qremesher. I don’t remember off hand, but “CSstiffness” may have served the same purpose as “curve strength” in Zremesher. I confess I dont’ have much experience with Qremsh as I never used it much, but Zremesher is great.
ZRemesher is the replacement for QRemesher. Lots of options with the new version, it’s great. I think there’s some videos on its use.

A must see

Zremeshing of open geometry is pointless, right? Because end of the model will never be like an original?

have you already press freezeBorder?
Nope, I was hoping there is something like this. 
But… where is this freeze borders? Update: I’ve found in decimation plugin.
It still looks like this:
Maybe freeze borders is also somewhere else?
Creating sound geometry is the preferred method. Looks like that tool is made of 2 parts you’re trying to remesh. Maybe you should split them up. Using delete loops in the geometry panel can be helpful. You can readily smooth an object once it’s created. Work low res to high as much as you can.
Oh, with the last model I was using remesh in subtool palette. Whats difference between remesh in subtool and zremesher in geometry palette? I already see that zremeshere isn’t making new subtool, just only changing existing one. If zremesher is better in remeshing, should I duplicate my subtool (for further projection) and use this modifier?
Zremesher makes much better, more intuitive toplogy, with far better options for fine tuning. It works magic for organic meshes. IT still has limitations for hard surface meshes though. You can’t magically create perfect box-modeled geometry with perfect edges for complex objects after the fact. If you need geometry of that precision, you’d be better off modeling the object from low poly to begin with, or manually retopologizing.
Subtool Remeshing can also combine multiple meshes into new contiguous geometry, like Dynamesh. Zremesher only works on a mesh by mesh basis. If you need a fused mesh, dynamesh the objects together first before Zremeshing.
Yes, you should duplicate the target subtool to be Zremeshed if you are going to be projecting detail.
You’re right. From disadvantages of zremesher, I don’t see symmetry options. I’ve made some topology tests. Results below.
Thanks you guys for precise anwers.
Zremesher uses the built in symmetry options. So if you have symmetry turned on, by pressing X (or in the Transform menu), when you press Zremesher button it will do symmetrical topology. I think it only has issues if you try to use radial symmetry, but x, y, etc. work fine.
You can also always Mirror and Weld any geometry after the fact if you forget to turn on Symmetry before Zremeshing.
Also, don’t neglect to use the Zremesher guide brush to draw guides for more control over polyflow. The Zremesher menu has sliders for determining the strength of these guides. If you have a particualr edge or area of detail you would like to be crisper when projecting, don’t neglect to make use of Zremehsers polypaint feature, which allows you to influence polygon density by painting either red or blue polypaint on the mesh prior to Zremeshing. I use this to help capture problem edges.
Higher values on the adaptive slider will capture detail and edges better on complex objects, lower values will make for more evenly shaped and distributed polygons. Some hard surface objects benefit more from one direction, than another.
