Yes I bought it too and found out that MSFS-Default mesh is more realistic in terms of actual shape and contour of various iconic peaks. Orbx has better snow rock texture.
These are screenshot of the Annapurna Range - Real vs MSFS, ORBx from third party pokhara airport.
REAL
MSFS-Default - much better
Orbx- Himalaya and Central Asia - Mesh is Broken
Hopefully they fix it.
