I'd rather choose Matic here since there's a lot of shit projects as well on BNB, and you can really see those projects dying the moment they enter in the market. TRON is not literally dead, it's just that developer see a good alternatives for this and with MATIC, I'm sure they can innovate more. If there's a new development with TRON then we might see new projects to come, but right now I can't see any worthy project to invest with, it's too risky to invest.
