    Use the ARB version. In general, always use the ARB version when dealing with extensions

    You can't use the sgis ones with register-combiners for example.
    But you can mix them if you don't use that. (on nVidia)

    The main difference is the ability to multicast texture coordinates. Using the ARB extension you must supply texture coordinates for each texture even if they are the same. With the SGI extension you can send the same texture coordinates to multiple texture units by sending the coordinates once.
