I believe bitcoincash (BCH) over Bitcoin (Bitcoin core),
we have no coin which is called "bitcoin core". there is bitcoin cash and bitcoin.
bitcoincash is the original that satoshi nakamoto wrote out as originally, the reason:
when you compare two things, you omit the things they share specially when you are saying one is better than the other because of ....
i don't know if you are just trying to make your list longer or just wasn't thinking but half your list is shared between two. in fact the only thing that you can
claim is not shared is the fees. now lets get down to it.
Bitcoincash is full of: "Low cosh transaction fees,
only because nobody is using it. it shares this attribute with at least 1500 altcoins with empty blocks which contain less than 20 tx. when you have blocks that are only 2-3% full (200-300 kB) you get low "cost" transactions.
Fast peer to peer transactions,
that is the attribute of any peer to peer network! you are sending a transaction which is practically some data on average 250 bytes with some overhead which won't even reach 1 kB which you will send/receive in an instant!
Reliable transactions,
i don't know what you have in mind when you say "reliable". care to elaborate?
Accept 0 confirmation transations,
that has never been a good idea. double spending a transaction with 0 confirmation is not as hard as you think. and from day 1 of bitcoin's existence i don't think anybody ever suggested 0 confirmation is safe and you started this topic with the words "Satoshi's vision"!
Decentralized development teams,
it is more centralized than you think.
research about how the fork for difficulty adjustment was performed....
Permissionless network and development,
you already said the development and the network is permissionless now but it won't last long if blocks start to become 8 MB and then they fork to 32 MB and running a full node becomes harder and harder and eventually impossible for regular people and you end up with centralized hubs which are the only option for you to connect to.
Open source code,
as if the rest of 1700 altcoins are closed source?
Limited supply (21 million coins), Proof of Work algorithm (SHA-256), Dates back to the Genesis block, Digital currency
well BCH forked from bitcoin's source code and shares all the consensus rules up to the date of the fork (~1 August) and nothing has changed in these consensus rules. as i said above these are not reasons for preferring it over bitcoin.
