Which credit card to use, by where you spend

Every merchant and spend category we track, with the top card and what it pays back right now. Open any one for the full ranking, the route, and what earns nothing.
No card paid to be here. A few have asked.
Every rate is read off the bank's own page and carries the date we read it. Every answer is worked out in your browser from that data - nothing is precomputed.
