No this is bad for example one of the later larger blocks

This is almost 3MB in size 3x the size of a block on BTC but only has 527 transactions in it every block on BTC has over 2000 transactions or 4x as many so for this 3MB block to compete with BTC it would need to be 12MB in size

The sat/b fee may be lower but the average transaction size is way bigger and this is really bad


See your chart here but instead of comparing blocksize compare the transactions per block

https://bitinfocharts.com/comparison/size-transactions-btc-bch.html#3m

The blocks may be bigger but the TX count which is what matters is only a fraction of the size this means the BCH blockchain will grow in size much faster than BTC while doing the same amount of transactions

At this rate you will be filling a 8MB block with ease but still doing less transactions than BTC
