Which one should you choose?
On price alone, Sumo comes out ahead in more of the networks they share. The gap in any one network is what matters for you, and it can change when either retailer updates its plans. If solar exports matter, compare feed-in rates on the specific plans. If you can shift usage to the middle of the day, look at time-of-use and Solar Sharer plans as well as flat rates.
