Ethereum is much better than Litecoin.. although Litecoin is a Lite version of Bitcoin but Ethereum is a core of many crypto coins, developers are very interested in using Ethereum (ERC20) than other platforms, this is the reason that makes investing in Ethereum is the best choice.
seeing between ethereum and litecoin I am still interested in ethereum because many ico or IEO users are using the platform from ethereum.
ERC20 is the core of many ICO / IEO circulating in the market.
I never considered Litecoin as one of top coins. Except of ethereum I believe in Waves, Stellar and some other, but not Litecoin.
IMO.. Litecoin is far better than Waves and Stellar, your assessment of Litecoin is wrong.
