"If someone can guide me, I want to buy the right Hornet die sets."
They all make good ammo, not really any difference in use. Since you ask I assume you are a new reloader? If so, it really makes no difference at all, selection of tools depends mostly on personal preference, it's not a "quality" thing at all. Some like Hornady's short bullet seating guide, some don't; Graybeaed does, I don't, just a personal choice.
