Should I pay for something with a BNPL plan or just put it on my credit card?
It depends on whether you'll pay in full and how disciplined you are. A 'pay in 4' buy-now-pay-later plan charges no interest if you make the four biweekly payments on time, which can beat a credit card you'd carry a balance on. But BNPL is easy to stack across multiple purchases and often doesn't build your credit, while missed payments trigger fees and possible overdrafts.
A credit card you pay in full every month is usually the better tool: it builds credit history, offers stronger fraud and purchase protections, and often earns rewards, all with no interest if you never carry a balance. The credit card only becomes the worse choice if you'd carry the balance at 20%-plus. Whichever you choose, the real question is whether the purchase fits your budget in the first place.
