Questions about Canon EOS 6D Mark II

which lens is actually sold with it? Is it the higher quality Canon EF 24-105mm, f/4 L IS II USM or the Canon EF 24-105mm - 3.5-5.6 IS STM? With the second, buying a set makes no sense.

Why does the set with kit lens cost 2499.-CHF and without lens 2079.-CHF? The lens 24-105mm - 3.5-5.6 IS STM shown costs only 369.-CHF individually or is there another lens in the set?
