Better Trees

Better Trees is a worldgen datapack/mod that reworks the way that overworld trees are shaped. It makes the vanilla biomes feel much bigger and more complex, and it works well with an overworld worldgen packs. Trees in this datapack are generally taller, and more complex looking than their vanilla counterparts, but still feel vanilla. Cutting one down will give you more wood and saplings.
If cutting down the bigger trees is too hard, try Timber datapack or FallingTree.
