In principle, both projects are developing in this market, have their own community and also have the potential for development and profit in the near future, so in my opinion, Tron and EOS can not serve as a bad tool as an investment. But EOS yet it seems to me some indicators of development slightly in the lead.
It's true that both cryptocurrencies have potential for growth in the future. Even if TRON is not as widely developed as EOS is, it could gain some attention from developers worldwide since it's an open source project. Anyone can largely contribute towards the improvement of the TRON project in order to make it a solid blockchain platform like EOS. But it seems that few devs are interested into TRON, relative to EOS and Ethereum.
Things aside, both EOS and TRON are very similar in the way consensus is handled. By using DPoS, they can achieve millions of TPS that's not widely possible in PoW blockchains like Bitcoin and Ethereum. Also, they have zero fees which is good for the crypto economy. While TRON is overhyped, it could be put up to good use if there's interest on it. Therefore, both TRON and EOS could survive alongside each other as they continue to build upon their existing blockchain infrastructure. Just my opinion
