What is the best GIS Desktop software?

Monde Geospatial at their FB site just announced that is it "QGIS". As this is from an independent party and not from me, I am so thrilled to read this news. Alhamduillah, Allah has guided me in selecting QGIS to promote to the Malaysian public sector. I am at peace with myself that what I championed for all this while was right all along.
