Better Security – BTC has a vulnerability called RBF which increases the risk of double spending. Bitcoin Cash developers aim to make 0-confirmation transactions safe again so that anyone accepting Bitcoin Cash is much safer accepting payments without having to wait for multiple confirmations. This RBF security vulnerability exists only in BTC and not Bitcoin Cash. That's why Bitcoin Cash is more secure as a payment method.
Here is an example of hackers stealing $150000 worth of BTC using the RBF security vulnerability. https://thenextweb.com/hardfork/2019/03/14/double-spenders-scam-150000-bitcoin/
It is super easy to double spend on Bitcoin using the RBF vulnerability. Source: https://news.bitcoin.com/video-shows-how-easy-it-is-to-double-spend-btc-using-rbf/
Lower Fees – One of the advantages of using cryptocurrencies over traditional payment methods is the low fees. Due to the limited block size of BTC, fees have exceeded over $70/transaction during peak period. On the other hand, I have never paid more than 1 penny/transaction during my entire time in using Bitcoin Cash. This makes using Bitcoin Cash ideal for merchants, businesses, companies and everyday usage. The industries that may be disrupted such as Remittances, Derivatives, Payment Gateways, etc are worth trillions of dollars and Bitcoin Cash is well positioned for use cases in these industries.
Improved Scalability – BTC is limited to 1MB block size and even with Segwit activated, the capacity increase is only around 1.7x whereas the upgraded Bitcoin Cash blocks capacity is currently at 32x with no limitations. This means Bitcoin Cash can handle PayPal transactions volume today and be global money after a few more upgrades.
Supply Scarcity – During the fork from Bitcoin, some Bitcoin Cash supply were removed from active circulation due to users unable to claim their Bitcoin Cash from unsupported exchanges and wallets among other reasons. This means each Bitcoin Cash is actually more scarce than BTC.
Improved Confirmation Times – Due to the limited block size of BTC, some users were made to wait days for their transactions to be confirmed. Contrast this to Bitcoin Cash where transactions may be accepted immediately with less risk and you can see why it makes sense to use Bitcoin Cash. In other words, if you are a shop owner and you just sold a cup of coffee and some sandwiches, and you accept the old BTC, you may have to wait hours for the transaction to be confirmed because the customer may use RBF to void the original payment. With Bitcoin Cash, your risk is minimized.
Higher Merchants Adoption - Bitcoin Cash is global money with more than 2,651,820 merchants accepting it. You can pay for your hotels, air tickets, food/drinks, groceries, nightlife, and more with Bitcoin Cash today. Source: https://1bch.com/?action=showBitcoinCashBenefitsFrame
While Bitcoin Cash adoption is growing very quickly every single day, Bitcoin is having declining adoption and if this trend continues then Bitcoin is on a dead end. Source: https://np.reddit.com/r/NotAcceptingBitcoin/top/?sort=top&t=all
Lightning Network Problems And Vulnerabilities And Loss Funds - Some people may claim Lightning Network will solve Bitcoin problems but it has failed to gain traction due to many problems and vulnerabilities, such as loss of funds, unreliable transactions (constantly failing), and many other vulnerabilities.
Be careful Of "Digital Gold" Or "Store Of Value" False Narratives - This is simple economics. Something cannot be a store of value without it first be a means of exchange. Bitcoin Cash is both a store of value AND means of exchange thanks to its low fees. Bitcoin is not feasible as a means of exchange due to its high fees of around $10 (or more) per transaction.
Store of Value: To act as a store of value, money must be reliably saved, stored, and retrieved. It must be predictably usable as a medium of exchange when it is retrieved. Additionally, the value of money must remain stable over time.
Bitcoin Cash Preserves The Peer To Peer Digital Cash Revolution - There are people who doesn't want peer to peer digital cash system to succeed. That's why Blockstream resorts to...
1c) threats and harassments
1d) DDOS attacks
1e) Plus a bunch of other unethical stuff
Anyone who dares to promote increasing the blocksize or favorably on Bitcoin Cash, they get banned and their voices silenced in the Bitcoin subreddit. They also get harassed and attacked by online paid trolls. Mind you, all these started even before the creation of Bitcoin Cash.
Tokens - Bitcoin Cash has tokens to start taking some marketshare from Ethereum. Today, anyone can issue their own loyalty tokens or digital money on Bitcoin Cash from as low as 1 cent to mint it. It's incredibly easy and anyone can do it at https://mint.bitcoin.com/
Increased Privacy - Bitcoin Cash has better privacy than BTC thanks to CashShuffle/CashFusion. You can enable it through the setting in the Electron Cash wallet and it's completely optional. If you don't want others to know how you spent your money, it is better to use Bitcoin Cash over BTC.
BTC started on the same blockchain as Bitcoin Cash but crippled the way it operates in order to force users into convoluted, patented "solutions" (like lightning) to transact. BTC intentionally can't scale (hence the "solutions" to "solve" this) and transactions costing upwards of $10.- USD (even for small amounts) aren't uncommon when the network is congested.
Blockstream and their investors use significant resources to manipulate planned operations to convey selected information to targeted groups and individuals in order to influence their emotions, motives, objective reasoning and to modify behavior while dissuading them from critical thinking or accepting factual information from the opposing side. the narrative and actively censor all of the primary Bitcoin communities such as r/Bitcoin. r/CryptoCurrency, r/BitcoinMarkets, mailing lists, Bitcoin Talk, wikis, etc. regarding all topics that have to do with these facts. (try it!)
The banking establishment has good reason to keep the population distracted with their artificially pumped, useless (for you and me) and harmless (to them) BTC. A decentralized currency would be their death.
