If I will choose between the two, I will go with SOLANA all the way.
TON only became popular because of meme coins and tap-to-earn projects, but do they have projects in different categories? I mean is there any exchange created under TON blockchain? In SOL, you have Jupiter exchange and pump.fun as well. In terms of sustainable growth, SOL will be the better one.
Disregarding these 2 blockchains, let's not sleep about SUI as well because there are many projects being created under SUI blockchain as well. Most are meme coins yes, but I hope that there will be more projects being created on that blockchain. It's just sad for me that I bought some at $0.70 a few months ago but sold it at a dollar.
