Bitcoin all the way because not everyone uses Bitcoin cash making their solution not that useful. Imo Bitcoin Cash's solution seems a bit rushed because if Bitcoin Cash was better a lot of people would've switched and their blocks should be flowing with transactions by now. The solutions we have with Bitcoin seems to be enough for now to maintain the low miner fee and if transactions starts to increase in the future there will always be a solution ready to be made.
i thought this kind of topic was probihibited here, well actually i dont know the answer i dont even use bitcoin cash. but bitcoin now has a development it was fast and low fees in transaction.
Afaik it's not, topics like these are only prohibited on r/bitcoin cmiiw.
