Cardio is definitely a better calorie burn. Are you doing intervals on any of your cardio days?
I do yoga on my rest day and for stretching on the other days. It keeps me lose, helps prevent injury and helps with combating imbalances.
Are you an emotional or stress eater? If so, it may be helpful on the nutrition side. My sister is losing weight after starting tai chi. She's not burning a ton of calories, but she said it has helped her overcome night-time eating binges. She's losing more from consuming fewer calories, not so much the activity.
You could always try it for a month and see if it works for you. And I promise it is much more difficult than relaxing on your couch at home.
