Yeah I found the same. Stuck to origin for me
Must vary significantly by location, I'm inner west (ish) Sydney and when switching between Red and Origin earlier this year for QFF points and SC both my old & new Red plans were cheaper than Origin.
Red (old plan): 83c supply, 26.2c/kWh peak & shoulder, 25.5c off-peak
Origin: 86.1c supply, 29.43c/kWh all times
Red (new plan): 89.9c supply, 21.8c/kWh peak, 22.5c off-peak
I also saved money when moving to Red from Alinta around 2018.
