It depends on your plans too. Plan to keep going for new bonuses? I read that article and know that at this point in my life, I'm not going to put any of those break even numbers on a Freedom or Unlimited in a year. Part of it is I've got other cards to spread my spending out on, because things will go on cards that earn bonus points for whatever category they're in. Also, I plan to keep getting cards. And unless other spending needs to move to the new card to get the spending bonus, I will keep charging things to their category cards and non-category spending will go on the new card. I went through this debate for myself and went with an Unlimited for a non-category spend card. Of course I couldn't have predicted what the Freedom categories were going to be, but it turns out they were very useful to me, and I almost never found myself reaching for the CFU because I'd grab the new card I was meeting spend on. I peeked through my statements: in the 6 months I had CFU, I put $2700 on it. Then back in April, I was sitting here all jealous of those with Freedoms because Q1 was easy to max, and so was Q2... when I thought, there's no reason I can't switch! So I did

Now I've put about $3500 on it, but I'd guess over 90% of that was category spend, so I'm way ahead on points. I put most non-category spend on a new card still. It's enough that I might turn my CSR into a 2nd Freedom card vs CFU for me.
So it comes down to: are you going to get new cards? maximize your points earning on your regular spending? carry multiple cards on you to maximize the spend? do you have tons of non-category spend? And if you pick one and decide in a couple months you want the other card, it's really easy to call in and switch
