As a general rule, heavier slugs penetrate well, faster rounds expand well. Again, general rule.
Living in Oregon, I favor 147gr Gold Dots. It's overcast here most of the year, so people generally layer. Because they layer so often, there is less incentive to be fit. Cliff's notes: we have a lot of heavy people in heavy clothing. Penetration is king.
The 147gr GDHP is also a light-recoiling round.
