You are confused as to whom you will listen. If you look at your list you are not just talking to one cryptocurrency but to a multiple cryptocurrency. Of course your mind will be confused since everyone of them will have their own view depending on the coins they hold. For example if you ask a bitcoin developer he will of course defend bitcoin and if you ask Vitalik he will say Ethereum is the best. So I suggest that we should not talk cryptocurrency as a whole but instead let us talk about a single currency and list people who have a say with that coin and let us decide to whom we believe.
I totally agree on this insight because I believe that the more we believe on others the more we got confused. It is very important to believe to those who can really explain and share to us what we need to do or things that are important so that we will be able to have a god output.
