I'm not an expert but a big difference is packet size: Sigfox is limited to 12 bytes, while LoRaWAN is up to 256 (iirc). Sigfox also imposes a max of 140 messages per day. Also, the governing body of LoRa is open (lora alliance), while Sigfox is closed. In general, the LoRaWAN approach is more open, with most if not all of the infrastructure being open sourced.
