I would like to align vertices to another vertex per axis. I know of scaling reset for all selected per sz0. However the alignment depends on other switches like proportional editing and so on which leads to lot of confusion. In Object Mode there is the nice align Object->Transform->Align Objects, I wish this for Edit Mode as well.
You can do this by setting the Pivot Point to
Active Element, then selecting the vertex you want all other verts to align to, last (the active vert has a brighter color).
Then you can scale in each axis to 0, and all selected vertices will align to the active vertex.
