I tried quinoa for the exact reasons you mentioned, but didn't find it nearly as palatable as more "traditional" staples. Compared to rice I found it didn't gel together when cooked, had a stronger (slightly unpleasant) flavour and a gritty texture.
In the end I couldn't justify the cost to eat something I just didn't enjoy. More power to those who enjoy it.
