The Leica has far superior glass to the Sig, but the Sig has the better RF unit onboard, and will range large reflective targets past 8000 yards. I see some shooters in the US have hit large reflective targets at over 9000 yards consistently.
In the end, you need to decide whether you want all the bells and whistles but glass quality is of a lesser importance, in which case the Sig wins the race, or lesser functionality but better glass (and 50%+ more money), in which case the Leica is the clear winner.
I'd say for mostly hunting, the Leica, and for mostly long distance shooting, the Sig. I've used both, and the above are my observations. And it's also the feedback I've been getting from my customers that have received these units already.
