I prefer multiple. Right now, I have a CFU with Chase and a BILT with Wells Fargo. I only maintain a Chase checking/savings account and pay my BILT bill through an external Chase account.
Keep in mind that most banks impose a soft limit on the amount of credit they’ll extend across their cards. With Chase, for example, they typically don’t exceed 50% of your gross income. So if you earn $60K, they might automatically deny applications if you already have two Chase cards with $15K limits each. Negotiating for approval often involves lowering the limits on your existing cards.
Be cautious as there are many on Reddit and other social media platforms promoting credit cards for clicks on their referral links. Their goal is to encourage you to obtain more cards.
I’d advise you to consider the value of multiple types of points, as they can often be worth very little.

Regarding the point about ‘multiple different kinds of points (all of which are worth very little)’:
I began collecting points two years ago and have since redeemed over $3K from money I would have spent anyway, without being a big spender.
Last year, my average was nearly $1,400 a month on credit cards, including utilities, insurance, and property taxes—which account for a large portion of that average.

If you lose a credit card while traveling, services like Visa Global Assist can send you an emergency card and cash. Additionally, if you still have your phone, mobile wallets can work even without your physical card.
