Best .45 acp ammo for Glock 21

Here next week I will be purchasing a Glock 21 an was wondering what would be the best ammo to feed it? I read on the "whats you carry ammo" that the people shooting .45 acp were mostly using Hornady rounds. Is that the best out there or are there better?

Price isn't all of that concern cause a lot of times in life, you get what you pay for.

Thanks in advance!
