I have an RX100 but considered the LX7 and a few others (Fuji XF1, another Panasonic with a tiny evf - can't remember the model, Canon S110 etc) .
They all seemed good in their own way but I liked the bigger sensor in the RX100 and my main priority after image quality was that the camera fits in a shirt pocket so I can have it with me almost everywhere I go. The LX7 was too big for that (otherwise I might have gone for one). But I also have an old Nex, so I am familiar with Sony menus and features like hand held twilight, panoramas, anti-motion blur etc.
The complaints in that link are valid (and some are addressed in the RX100ii but that is almost double the price). The 'macro' is not the best but you don't need to choose 'macro mode' you just use it at the widest focal length and f1.8 as close as you can get to the subject (about 5cm?) and it works fine apart from occasional mis-focus. Not bothered about neck strap attachments or a hot-shoe and an evf would be nice but an add on one would be too expensive and too much hassle and a built in one would either mean the camera would be too big or the evf would be awful like the little Panasonic one - so I can live without that.
By the way the built-in flash works quite well when pulled back and bounced indoors and outdoors you can even use the flash at a shutter speed of 1/2000 should you wish to.

You can also use the pop-up on the RX100 to trigger a slave eg a cheap Yungnuo flash with two slave modes S1 and S2 (to ignore the pre-flash) although that of course means you have to carry a massive flash around along with a tiny camera.
But if I want to get serious about flash photography or macro I have a dslr for that.
This guy went from an LX5 to an RX100 and seems happy enough:
