Looked at and drove same choices recently. Kept coming back to MB GLC. Two things stopped me...the seats were definitely not up to MB standards. Comfortable for short trips but wearying on longer ones. And I really dislike immovable ipads tacked onto the dash on any car.
I ended up buying CPO A7 Prestige. It has Mercedes E class ride and quality, a hatch with more room than any of the suv's already discussed, great seats, and the iPad disappears into dash when not in use for a very clean Audi interior.
Obviously not a trail vehicle. But totally worth that tradeoff to me because once you get a taste of A7 fit, finish, ride, quality, and overall solidity on the road compared to the other vehicles I tested discussed above (including the Volvo, BMW, MB, Jag, Q5, plus JLR offerings) it was obvious that there is a huge gap between vehicles built to a $40k price point and those built to a $70k price point.
Full disclosure: we own a GLK 250, my wife's car. Fantastic vehicle. She loves it. That's what made me favor a GLC for myself. Until I saw what I could get for the same money in a CPO A7.
