Ethereum > Litecoin. It's got more support and a bigger user base as well. Also, I'd say that people accept Ethereum much more than Litecoin in general; more people hold etherum than they do litecoin. For example, recently I ran into the Enjincoin ico project, and I was surprised that they weren't even accepting Bitcoin -- only Ethereum. Struck me as odd at first, but it seems like Eth is a very preferred altcoin.
