I personally feel that Tron has amazing potential. It might not be that dazzling technically but the marketing is amazing and good marketing can make or break a good product.
As for ETH, unless they fix the scalability issues soon, there would be trouble in paradise.
About bitcoin say the same thing and what we see at the moment? Nothing has happened to him, and it will not happen, the same goes for ETH, and the potential of this coin has not yet been revealed, we will soon see all this.
