It ultimately depends on personal preference and what you enjoy doing in Minecraft.
In Creative mode, players have unlimited resources and can build and create without any constraints. They can also fly, which can make building and exploration easier. This mode is great for players who enjoy designing and constructing elaborate structures and worlds, or who just want to have fun and be creative without worrying about survival elements.
Survival mode, on the other hand, adds a number of challenges and gameplay elements that make the game more challenging and immersive. Players must gather resources, craft items, and defend themselves against mobs in order to survive. This mode is great for players who enjoy a more challenging and realistic gameplay experience, and who enjoy the thrill of trying to survive in a harsh and unforgiving world.
Ultimately, it's up to you to decide which mode you prefer. Some players enjoy switching between the two modes depending on their mood or what they feel like doing at the time. Both Creative and Survival modes can be enjoyable and rewarding in their own way, so it's worth trying both and seeing which one you like the most.
