I've had the Canon G9X for a couple of months now and highly recommend it. Great UI with mix of touchscreen and physical controls.
Smaller than the competition - truly pocketable.
Doesn't seem to have a lot of love on the forums (the big boys prefer the G7X apparently) but I'm very happy - I tend to use the 28mm end and rarely zoom so the relative lack of long focal length coupled with that slow f4.9 doesn't really bother me. And I prefer the fast 28mm wide end to the 24mm of the other cameras.
Of note I did have the RX100 Mk1 (broke recently after 4 years, well, actually, I dropped it on a tile floor!) and the Mk 3 (sold it on as I didn't use the bells and whistles). The RX100 mk1 is an excellent camera too but the Canon is smaller with a much better UI and the WiFi implementation is excellent.
The LX 100 is a different (bigger) kettle of fish, to my mind.
Canon is also cheapish and has a £30 cash back currently.
