I'd like to add another camera to my collection, to complement my two current main cameras (an Olympus XA2 and a Pentax K100). I'm having trouble deciding between an Olympus 35 RC or a Cannon Canonet QL 17 GIII. Does anyone have any advice or suggestions?

(Also, does anyone have suggestions for film? I'd like to break away from the standard Kodak or Fuji for a little bit.)
