I just want to use Bitcoin as a currency. I honestly do not care too much about the small differences between the two chains. They both have SegWit which will allow the Lightning Network which will allow for fast, cheap microtransactions.
Not really. BCH doesn't have Segwit, doesn't fix tx malleability and obviously LN can't play with tx malleability without other workarounds (?). It's just "bigger blocks".
Didn't BCH fork off after the Segwit lock in? Or did they fork with a version that did not include it?
