i'm not agree with u , cuz i don't think that ADA and IOTA in competition because of they r tow different coin with defferent technology and goal
each coin has a goal and a separate challenge  , while IOTA is envloving into internet of things and creating the technology to manage IOT using tangle technology which is a way defferent to blockchains trying to solve the blockchain problem
we have ADA who comes to us with big project and creating a new generation of blockchains that using smart contract 
but i think that ADA and IOTA is the most up coming coins giants in the near future
