As far as I can say, Solana is a good blockchain. It's backed up by FTX, also a good exchange. Solana ecosystem is growing rapidly. But to say Solana will surpass Binance Smart Chain is uncertain. The only downside of Solana is inconvenience. Using Solana, you have to create a purely new wallet that is generally called "Sollet", while you can use a same wallet address for ETH, BSC and Matic on Metamask. Low fee is just a thing but it won't make a lot of sense regretting a fraction of dollar per trade when switching from Pancake to Raydium.
