Are there any tools, plugins or methods in QGIS which allows for an analysis of the best path between two points using least cost path method? As shown below ArcGIS has several distance tools.
There are number of tools from GRASS and SAGA which allows for cost analysis which you can access from the Processing Toolbox:
If you want to compare vector-paths the "Road Graph Plugin" is working fine. If this is interessting for you dont forget to use the "Topology Checker" before analysing the data.
