What are the differences between chain wax and lube, and which one is more effective for maintaining a bicycle chain?

Chain wax and lube are both used to lubricate bicycle chains, but they have different properties. Chain wax is a dry lubricant that creates a protective coating on the chain, while lube is a wet lubricant that penetrates the chain's links. Chain wax is more effective for maintaining a bicycle chain as it repels dirt and grime better, resulting in a cleaner chain and smoother performance.
