I assume you mean SMBus. They're nearly the same thing. Maxim has an app note on the subject.

It was in relation to the TAOS light to digital chip that says those are the two types of interfaces ...

Since one version of the device is I2C and the other is SMBus, I'd pick the one that was easiest to interface with my microcontroller of choice. I think you want the I2C version (2561) with the Arduino/ATmega.
