In his Basic Design of Experiments Mastering JMP session, Bill Worley @bill_worley suggests using D-Optimal if you want the best parameter estimates for the model. Use I-Optimal for the lowest prediction variance. If you think there is curvature, consider using I-Optimal, which will force mid-points into the design.
