Minecraft wiki entry for Best_biomes_for_homes, associated text: It is the least hostile Nether biome.
Wood can be obtained from blue warped fungi trees, a necessary material for long term survival.
Nether fortresses cannot generate in a warped forest biome (although they can generate into one if a neighboring biome generates the fortress), meaning blazes, wither skeletons, and normal skeletons will likely not be encountered.
As with all Nether biomes, striders spawn in the lava lakes in this biome. For the player's safety, this is the best biome to house them in.
The warped fungi found in this biome can be used to ward off hoglins in the crimson forest.
Twisting vines are a flora that grows upward-similarly to kelp-that can be climbed like a ladder. Unlike ladders, they do not require a support block to be placed (aside from the block the bottom vine is placed on), meaning they are excellent for scaling cliffs or reaching higher levels of the Nether.
Thanks to the increased spawning of Endermen in this biome compared to the rest of the Nether, this biome makes an efficient place to gather ender pearls.
