LG V20 - What's the diff between the model # LS997 vs LS996?

[superboy]

Hello.
I'm currently on Sprint and have been looking at some preowned LG V20s but I've noticed 2 diff models, the 996 and 997. What's the difference between the two? Which one's better? Thanks.

Welcome to Android Central! The LS997 is the V20, but the LS996 is the G Flex 2:

LG V20 Sprint (LS997) Android Smartphone in Titan | LG USA
LG LS996: G Flex2 Sprint Smartphone in Red | LG USA

EDIT: It looks like you're referring the US996 (http://www.lg.com/us/cell-phones/lg-US996-Unlocked-v20-titan). But US997 refers to the G6: http://www.phonemore.com/compare/phones/lg-v20-us996-vs-lg-g6-us997/5266255
