Best self defense load

[Remington700]

I have been researching self defense loads and what is best. Of course "best" is typically an opinion. I feel like any hollow point that has good expansion and penetration is good.
Reading is seems that most people like HST or Gold Dots for EDC. I am older, so I have several silvertips and hydra shoks. These in most write ups are considered old technology and not as good. What are your thoughts on self defense loads/ what do you carry in yours?

Years ago I did a deep dive on various 9mm self defense ammo and finally settled on the Federal HST ammo. I carry 124 grain bullets in anything sub 4 inches and 147 grain bullets in anything with a 4 inch barrel or more, all in standard pressure. I believe the HST ammo checks all the boxes in the consistency of penetration and expansion in anything you may encounter.
