The honest take

Who wins?

TXU and Reliant are both NRG-era mass-market retailers running nearly identical bill-credit playbooks. At most usage levels the effective rate gap is tiny (0.3–0.8¢/kWh), but neither is ever the absolute cheapest plan in Texas. If you're price-sensitive, both will cost you more than a mid-tier retailer like 4Change or Gexa at the same usage. Pick one only if brand support matters more to you than saving ~$120/year.
