Can Someone Help Me Understand Energy Rates?

So I was with entrust for years and after the freeze they went under and I was absorbed/brought into Rythm. Usually my bill hovers around ~$200, but this last cycle it was almost $300. The breakdown on the bill is as follows:

Energy Charge 1,259 × $0.18835 per kWh = $237.13
TDU Delivery Charge = $52.23
Misc = $5.78
PUC = $0.47
Tax = $2.95
Total = $298.56

Using the power to choose website I see Payless Power offering a 12mo fixed rate of $0.137 per kWh at 1000 kWh, which is around my average usage (almost always 1000-1300). It says disclosure is based upon:

Energy Charge = $0.0945 per kWh
TDSP Delivery Charge = $0.038 per kWh; passed through based on daily usage
TDSP Monthly Charge = $4.39 per month

Would the Payless Power fixed plan save me money? I've been on Rythms "Texas Flex" plan for more than a year since my bill has never really been an issue before and shopping for energy is intimidating to me. I really appreciate any help that can be provided to clarify and explain things to me.

Thank y'all!
