I think Litecoin is firstly more estabalished with new features being introduced along the way like the Pay feature in addition to better acceptability & recognition vis-a-vis NEO (as of now) and should touch $1000 in 2018 before NEO.
Whats your view...
I will put my bet to NEO as this is the China version of bitcoin, sooner the price will become huge as the demand of cryptocurrency in Southeast Asia is now increasing. With their proven product this could attract more buyers.
