The lack of a nearby train station means Market Mall enjoys one huge advantage over Chinook Center: teens. I am no statistician, but on an average trip to Market, I notice about 35% less teens there than at any given time at Chinook, and it makes for a nicer shopping experience. The mall is laid out like a giant ring so you can do all of your shopping in one lap without need of a second level. The store selection is better at Chinook, and ever since Play closed two years, there has been little reason for me to come here other than a change of scenery from Chinook. However, it does have decent food court options (including UMI sushi), and Kat usually has better luck in Market's female-targeted stores than at other Calgary malls. I have yet to find the fabled underground garage: I usually come off Shaganappi, so I suspect the entrance is on the opposite side.
