The sensor specs favor the RX100 but the brighter and sharper LX7 lens often makes up for its lesser sensor.

This is a common misconception.

LX7 does not have a faster lens.

LX7's lens is 4.7mm F1.4, aperture is 3.6mm in diameter, actual opening is 10.2mm2

RX100's lens is 10mm F1.8, aperture is 5.6mm in diameter, actual opening is 24.6mm2

RX100's lens lets in 150% more light. it is much much brighter.

LX7's lens is 17.7mm, f/2.3 = 7.7mm aperture diameter (at the long end)

RX100's lens is 37.1mm, f/4.9 = 7.6mm aperture diameter

So, at the long end the LX7's faster lens actually does make up for its smaller sensor when shooting in low light (because the LX7 can use a lower ISO).
