The power ratings don't appear that much different, but I think the 251 is a more comfortable engine to drive. In some places, you see the hp listed around 120. But I am not sure how much faith I would put in HP ratings over a period of many years...a lot of this was driven by marketing.
I have one PW with a 230, one with a 251 and I think the 251 does better. They also have a shorter stroke so should be a little more rev tolerant.
In general, the 251 series (made in many displacements) is stronger than the 230 series.
