My first experience with using (ASTER) GDEM:

It is an excellent product (better than SRTM DEM) and easy to obtain

It is an excellent product but difficult to obtain

Positional accuracy is satisfactory, but resolution needs to be degraded

18%

Neither positional accuracy nor geomorphologic plausibility are satisfactory

27%

SRTM DEM is still more usefull

55%
