The minor differences in bullet performance are overwhelmed by errors in bullet placement. Choose something you can afford to practice with enough to be sure you can place the bullet where it needs to be.
Ranger-T, Gold Dot, HST, Golden Saber, whatever, I stock up when its on sale, and worry a lot more about my skill in placing it on the target than which bullet it is. No magic bullets for me. I want to have shot any carry ammo enough to be sure they are reliable in my gun and my POA/POI is correct.
Unless the price is really outstandingly good, I buy the heaviest bullet for the caliber -- 147gr in 9mm, 180gr in .40S&W, and 230gr in .45ACP.
