They are only good at business, I see little creativity in BSC projects because they are mostly projects that are copied from each other and Ethereum.
BSC is just a high-speed, low-cost version of Ethereum. I do like the advantage of BSC though, as they drew developers from their rival Ethereum.
This might be a big advantage for BNB against Ethereum in the long run actually. Because people prefer a faster network and lower fees first. And it needs to be secure also of course. As long as BNB provides these conditions all the time, BNB may draw many more people's attention to itself. However, I've been hearing that BNB fees are also starting to be expensive. This could be a bad sign for it if its developers don't create a solution for it.
As I said, the ecosystem needs creativity instead of copying ETH.
The advantage of BSC is only cost and speed and the support of CZ. He has many tricks to increase the value of the Binance coin.
The issue of speed and cost on Ethereum will be solved after ETH integrates technology from Polygon and moves completely to POS. Time will tell whether BSC or ETH is better.
