It’s compatible with ArcGIS, however, so QGIS users can still accept and work with ArcGIS-specific files.
 

Why ArcGIS is better than QGIS?

QGIS is much faster than ArcGIS. Reliability: ArcGIS has better spatial topological analytical capabilities and provides more reliable results. The value of cluster tolerance in arc map is limited to 0.0000009.
