if all you care about in a cryptocurrency is the speed of transaction and the "charges" or in other words paying lower fees then use Dogecoin or even Reddcoin (RDD) you can even send them with zero fees and get confirmation in a couple of seconds.
True. While there are many other altcoins, that are quite much faster than LTC, there are a very few which have Litecoin's value proposition. In other words, since Litecoin is much older than most altcoins, it has better security (due to established nodes), a higher hashrate, and others. That is why it is sometimes seen as silver to Bitcoin's gold.
But still, if you only want to transfer coins in a near instant way, then you could always choose from the wide array of altcoins which have smaller networks, cheaper fees, and are good for micropayments like Reddcoin.
Testing out different altcoins myself, i'd say that Ripple is the fastest one in transaction confirmations. It has good features and all, but the only thing that it lacks it is true consensus, not to mention that it has a centralized model.
Nevertheless, I hope that Litecoin could make the difference among the wide array of altcoins, if SegWit becomes activated on it. Just my opinion.
