You can build lots of things if you are a pro. Creative mode is better than survival mode, you can get all of the things you need in creative mode. Things that are hard to find in survival mode you can go creative mode so that you can get of all the impossible blocks which you can get in survival mode. Hardcore mode is the hardest thing in Minecraft, In hardcore mode, it will be locked at hard, so you have to pass hardcore. So creative mode is better than these two modes. Creative mode is the nicest mode ever because like blocks from the nether which is a biome in Minecraft, how you enter the nether is that you first build a nether portal, and then you may spawn in the warped forest biome, the crimson biome, and the soul sand valley or even right by a bastion. Also, the nether fortress is the greatest thing ever in Minecraft because you can fight blazes to get blaze rods and you can kill endermen to get the ender pearls but you can only do that in survival mode. Because if you are in creative mode you can get blaze rods and ender pearls in the miscellaneous tab. But if you are in survival mode and entered the nether and when you spawn in a nether fortress, you may want to get looting II and mending on your diamond sword.
