The fact you ask here might be biased but do remember more coins bought=more profit if the price were to skyrocket...diversify though also.
This is a fallacy, profit comes from the percentage increase in the coins value. A lower price coin doesn't make it any more likely to moon. A lower market cap coin has a higher chance to moon since it doesn't take as much capital inflow to move the price.
To answer op question I would diversify into both coins but what I hear you asking is what coin offers most value at today's price. Bitcoin has taken a huge jump recently and it may be due a correction whereas litecoin has been moving sideways and could break out soon.
However, asking a litecoin Reddit is likely to yield a skewed response.
