Not spectacular, but you also need to compare this to whatever alternate investments you would have chosen at that time, and would have kept until now. Gold, Cash, small caps, real estate, multi-factor, managed futures, ?
You also need to consider why you have chosen these to points in time.
Looking backwards, there were probably better things to do with your money during that specific time period, but would you have chosen them in 1996 ? And would you have kept them until today ? And, if not, would the changes you would make have also done well ? You would need to be right in both investment selection and timing many times to have done better than the SP has done.
