Lists that rank cryptocurrencies can give you an idea of how popular they are... but they dont tell you which one is the best. Each cryptocurrency has its own special things that it can do and different ways it can be used. What might be good for one person's investment plan might not be good for someone else.
I think rank is a standard indicator of the assessment of a coin in CMC based on population and market cap. If you say the highest rank is not the best, then who has the right to give an assessment. Do you ?? I think we have to talk realistically based on data, if a student becomes the best graduate, he is the best.
But if you think about who is more interesting to discuss, can play guitar and sing, not necessarily him / her.
I think litecoin is very potential coin, and but cardano is better..
