I will always choose ETH above LiteCoin. Over 70% of blockchain projects are running on top of ETH blockchain infrastructure. So, if it is for long-time investment, then ETH is preferable for me most especially when they have Sharding in the pipeline to implement in ETH 2.0
It's not about how much platform that runs on ethereum blockchain as its parent platform. The fact that ethereum has more utility usage compared with security token like litecoin. that makes sense to owned more ethereum rather than litecoin. ETH 2.0 is not yet begin and again the price of ethereum and litecoin were going down sharply.
ETH is much better and sharding is nothing compared with its utility usage that makes ethereum can't be considered as security.
