You don't "need" to use the most expensive ammo for carry, but that's not the same thing as saying that you're not getting something concrete for the extra money spent on premium quality self-defense ammunition.
Buying and carrying premium self-defense ammo for carry doesn't preclude actual preparation.
For example, I have found a practice round that prints to the same place as my carry round does. I've shot enough of my carry round to verify to my satisfaction that my carry gun will function reliably with it and to verify where it prints. When I practice with my carry gun, at least some of that practice is done with my carry ammo--but most of it is done with the practice round that prints and shoots like my carry round.
In other words, preparation doesn't have to mean that you only shoot the cheapest stuff out there so you can practice a lot with it, nor does it mean you only shoot the must expensive stuff you can find. You can get a lot of good practice with inexpensive ammunition and put in enough practice with your carry round using premium ammunition to make sure it works and prints properly.
I remember when one of the strongest justifications for reloading handgun ammunition was that it allowed a shooter to create a practice round that duplicated a person's carry loading to allow them to practice without burning up expensive carry ammo.
