The answer to 'which is better tree removal or' is that tree removal is generally better than tree trimming or pruning when a tree is dead, dying, or poses a safety hazard. Tree removal involves completely removing the entire tree, including the stump, while trimming or pruning only removes certain branches or parts of the tree. Tree removal is the better option when a tree is beyond saving and needs to be taken down entirely.
However, tree trimming or pruning is the better choice when a tree is healthy and just needs some maintenance, such as removing dead or overgrown branches. Trimming can help a tree stay healthy and look its best, while also reducing the risk of branches falling and causing damage. The cost of tree removal is usually higher than trimming, so if the tree is salvageable, trimming may be the more cost-effective option.
