Intro APR winner

Chase Slate Edge
Why it won
The intro APR offer category is where the Chase Slate Edge really shines, since this card gives you 18 months with 0 percent intro APR on purchases and balance transfers, followed by a variable APR of 18.99 percent to 28.99 percent. This offer is three months longer than the offer on the Chase Freedom Unlimited, which only gives you 0 percent intro APR on purchases and balance transfers for 15 months, followed by an 18.99% – 28.49% Variable APR.
Both cards also have the same intro balance transfer fee of 3 percent with a $5 minimum for the first 60 days from account opening, after which it rises to 5 percent with a $5 minimum.
