S3 is the original OO approach in R. It is the predominant one and the simplest one. That's the one to use if you are starting out. You may never, in fact, need to go beyond that. S4 builds on S3 so learning S3 won't be a waste of time even if you decide to use S4 later. S4 is substantially more complex than S3.
There are also a number of packages that implement alternative OO models. R.oo implements a model closer to the conventional model that other languages use. proto implements the prototype model, particularly applicable to user interface work.
