to be fair, Lightning has the minor problems that (a) it doesn't work (b) if it did work it would be a pretty dumb payment system (pre-filled channels for everything?) (c) bitcoin had no merchant case when transactions weren't clogged anyway (and the merchants haven't come back now it's unclogged). I've got 4000 words of a rambling draft on why Lightning sucks in every conceivable aspect which I might finish one day.
OTOH, what Litecoin really has going for it is being listed on Coinbase/GDAX. This is super-important because this means it can be traded directly to and from actual money (and not Tethers). Retail buyers during the recent bubble were literally choosing to buy LTC because they logged into Coinbase and it was "cheaper" than BTC.
