RX100.
I also have and often use a G15 and a G1X, but don't consider either to be true pocket cameras, although the G15 comes close.
Also still have and sometimes use an S95, but primarily because I bought an underwater housing for it and that's more or less become its exclusive use.
I understand those that mention handling difficulties with the RX100, but I personally haven't found it to be a true problem, I just taught myself how to handle it without dropping it (not that hard), and have been very pleased with image quality for a camera that actually does fit in your pocket. I have successfully produced and sold relatively large prints from it. Better, in my opinion, than those produced from either the G15 or the G1X.
Bottom line, for me, RX100, followed by S100 (agree with Neuro on S110).
