Well bitcoin achieved huge sucess because it were well made, since the begining and the core now just improve it, and has some questions to handle over the next years, but hasnt any influence neither being controled by just one single person. I dont know how sucessfull a new crypto coin with a team and control may achieve sucess, but its good for crypto world.
I agree, atleast now no crypto currency is even near as succesfull as bitcoin is. The first time i heard of bitcoin, I didn't even know that there's some other cryto curriencys as bitcoin. I believe that's becouse media is mostly posting about Bitcoin.
