Well, both projects are actually among the top ones, it is not like the author of the thread is asking us about some shitcoins. Tron is promising to build its decentralized massive network. It is good that it already has a lot of support and thus financial means to do that, but I feel like the team might turn out to be not up to the problem. I am not sure they are even trying to succeed, as the token is successful anyway. As for Cardano, it might be a good platform in the future, so I suppose it is a nice investment. Not to fail, though, I would recommend to invest some money into ethereum as well as bitcoin. Diversification is always a good thing, because if some of your investments fail, at least others can compensate them.
