All 3 are great motors. More ports will give you more top end.. So for the long straight the RB S9 with it's 7 port will give you the highest top end. The Plus 4 and P5 are similar on paper. The plus 4 is more popular since it's a new design and the P5 has been revised and updated through the years.
