Keep RX100 or sell and get Nex6?

Hey.. I've bought RX 100 for 2 months and found out that the 28~100mm CZ f/1.8~4.9 Vario-Sonnar is excellent. You will need to consider that lens quality also. If you are planning to use only 1 lens (zoom, I suppose), you will hardly find the same quality w/o paying $$$..
