TRON platform will have the most dapps in a few weeks
EOS and ETH are like myspace and friendster
TRON is like facebook
We'll see. AFAIK, Ethereum is the most popular smart contract to date. For TRON to beat Ethereum and EOS, it would need to gather the same or greater level of adoption within the mainstream world. As far as ETH and EOS goes, they both have huge potential of becoming largely adopted by serious businesses and companies around the world. EOS is highly scalable with zero fees, whereas ETH is secure and reliable.
On the other hand, TRON is good, but it doesn't have the same traction as ETH and EOS. Of course, we cannot deny that TRON is highly scalable the same way EOS is, since it uses nearly the same consensus algorithm as EOS (known as DPoS). An advantage that TRON has over EOS is that it's largely compatible with Ethereum's EVM. That's not possible with EOS, since it has its own VM which is incompatible with the EVM. Putting technical things aside, both ETH and EOS may survive after all because of their dedicated development teams, and ever-growing community support. Just my thoughts
