Unless you need to construct a ProfiBus network, go with Kit #2. Establishing a Profibus network requires an external power supply, Profibus connectors, devices with Profibus communication capability (drives, scales, etc.).
Both kits would essentially be programmed the same but may require different drives on your PC. When you buy a starter kit, those drivers are included, as well as the cables.
If you have a question about a particular starter kit model, please post the part number along with your question.
