My dark souls hot take is that playing without any form of guide offers the most fun and rewarding experience. People get fomo about missing out on dialog, or optional bosses, or weapons, or treasure. But I think that's part of what makes the game great. For exploration to feel truly rewarding, you must allow the possibility for the player to miss something. The game has plenty of content to see and do even if you don't discover all the secrets.
That being said, people disagree with that and that's okay. Some people don't care for exploring, some people hate the idea of missing out on stuff. If you really want to not miss a thing, a guide will do that for you. Some people play through the game once blind and then go into Ng+ with a guide which is also valid.
