A buddy of mine has had an A5, S5 sportback and his wife currently has a Q3…fine cars but the handling is not on the same level, you feel the weight over the nose in the Audi, for reference my wife and I have had a 2008 M3, 2011 335, 2014 328 touring, currently 2018 M3 and 2021 X3, so we were able to compare…otherwise it’s a question of what you like…I prefer the angular design of my wife’s X3 to the Q5 but they both look better than the GLC
I think a few things would be pretty darn close and come down to taste, I agree the Audi wins on road comfort but our X3 came with Msport which kind of makes no sense on a hybrid but we had limited choice in the middle of the supply crunch
