I would go with the X9. All the tutorials ( https://hackaday.io/project/144350-hack-35-activity-trackers-for-mental-health-more ) are geared towards the X9. The PCB test pads are big and easy to solder. The HR sensor is a simple LED/Photosensor breakout. Haven't gotten DFU working yet, that is definitely on the list.
