Bitgert blockchain is faster, and the gas fee is cheaper than Polygon.
It's faster, cheaper for each transaction, which is definitely more when compared to Polygon Matic, but the problem is, is there anyone who wants to use the project's blockchain?
Polygon Matic already has lots of features that can be used on various platforms, such as playing games, NFTs, zkEVM for Rollup Ethereum L1 changing to Ethereum L2 and many more.
If Polygon Matic's competitors only rely on speed and cheap transaction fees, it seems they don't have the power to compete with Polygon Matic, because everyone knows that Polygon Matic has lots of tested features.
