a few quick points.

raising is better against passive opponents since they will check to you and its easier for you to get to showdown unimproved with the best hand.

raising, however, hurts your earn when you flop sets, since players wont give you mcuh action.
edit: this is not true for this examle since there are gonna be so many callers that you are getting close to the requisite 8:1. however, if the pot was gonna be 3-5way it would hold

raising helps your earn when you win unimproved since you are taking advantage of an immediate equity edge.
