In the last period ETH is somewhere around 20M dollars in fees per day, while BSC is around 1M. Note that the ETH fees are split between all the ETH miners, while the BSC fees are split just between the 20 BSC validators/bloc producers, because BSC is a proof of stake blockchain.
On one occasion ETH had 55M USD in fees per day!
In terms of fees per transactions they depend on the level of the activity on the network, but overall on ETH they are in the range of 10$ for simple transfer and up to 50$ (sometimes more 100$) for a smart contract operation. On BSC these fees are in the range of 0.1$ to 1$.
