The main difference is not the core machine, but how the Smart Pro is packaged and licensed. ADD-TT0424XXXX is listed as the Smart Pro custom / hardware-only option with 1 month of UTP and a flexible pay-as-you-go model, while ADD-D757554AD is sold as the Smart Pro with 6 months UTP. In other words, both are Smart Pro platforms, but the included usage plan is different.
Based on the published descriptions, the higher price on TT0424XXXX does not clearly mean more programming capability. The clearest published difference is that TT0424XXXX is the custom hardware-only route, while D757554AD is the 6-month UTP package.
