How does the EDS-TX compare to Shimano Di2 or SRAM AXS in price and features?

At ~$419 (front and rear derailleurs included), the EDS-TX undercuts Shimano Di2 by $200-300 and SRAM AXS by $300-400 while offering dual wireless protocols (BLE + ANT+), app-based tuning, and cassette compatibility up to 36T. You'll sacrifice some brand ecosystem integration, but gain significant cost savings and the flexibility of the optional carbon fiber OSPW cage upgrade for fine-tuning performance.
