My friend Mike has full suntour group on his Miele and rides with me daily (6x2 gearing) and he has Look pedals from about 15 years ago. My shoes clip in fine and vice versa, they obviously haven't changed anything.

Goto a LBS and try the different pedals if you can...I have SPD's on my mtn bike but am very happy with my LOOKS (I was goin to get Campy pedals but one ride on the cheapo looks and I was sold)
