Let's go backwards a bit. The genesis block of Bitcoin launched in X. Forward to X and Litecoin forked from Bitcoin.
Some notable differences...
litecoin is cheaper, faster and you'd use it to buy your coffee. it needs greater adoption but its getting there fast. it can also latch on to other services quite easily such as bitpay, shapeshift.
both are solid long-term investments on the business side, depending on your situation, it might be a good idea to hold on to a few of those coins rather than immediately turning them into fiat currency.
