I think we should compare within the period I specified
That is, the period from the recent bottoms (both Litecoin's and Bitcoin's earlier this year) till now, and within this period specifically Litecoin is still a better alternative to Bitcoin if you primarily aim for speculation.
Litecoin is now underperforming since the bottom and is at its lowest ratio since 12-2017.
Whoever held on halvening hype got rekt.
