I prefer the Federal Premium 147gr HST hollow point. ATK Law Enforcement has tested the round against other "duty rounds" provided by departments. They go out and set up the test where the local LEA can watch and then submits their report. The HST tends to be the top performer in 9mm and .40S&W.
Through a car windshield the Winchester SXT 147gr will penetrate better. However, the HST retains more weight and expands more effectively. The HST still gets 7.5" of penetration after going through a windshield. So, it is still very similar to being hit with a .380.
My second choice is Speer Gold Dot. They tend to penetrate a little more than HST rounds of the same weight. However, they don't usually expand as well.
Golden Sabers are great at penetrating. In balistics gel the 147gr has been know to get 15" of penetration. However, they expand about 38% less than a Federal HST 147 grain round. So, you have to decide if you want an extra 1 - 1.75" of penetration or an extra .16" of expansion.

The ammo can usually be found at Ammo To Go for about $35.00 for 50.
Not all hollow points are made the same. I have tested MagTech Guardian Gold in a Taurus PT92 and a Kel Tec PF-9. There was no expansion when fired from either gun. They were fired from ten yards in to water filled milk jugs. With the water they should have shown optimum expansion. All ten rounds completely failed to expand.
In similar personal testing Hornady Close Quarter LE 147gr factory loads tended to expand less, but penetrate more than Winchester Silver Tip 147gr factory loads. The Winchester was originally designed for an old FBI protocol that emphasized temporary wound cavity over penetration. This can be seen when you test it beside similar hollow point bullets.
