Which is better, Canon 60d or Canon 70d?

60D pixels18 million; 70D pixels 20.2 million; Sensitivity: 60D Basic shooting area mode: ISO 100-3200 automatic setting; The basic shooting mode of 70D is automatically set between ISO 100-6400;

70D > 60D: multiple exposures; Electrostatic capacitance touch screen technology; Built-in Wi-Fi function.

I suggest you choose 60D and use the extra money to choose a good lens.

The following figure is a screenshot of 60D+ 18-200. For your reference (this was shot with the worst focal length of 200mm):
