I've had both. In 2011 I bought a 2011 Fiesta SES. Had that for 5 months then traded it in for the Focus. Fiesta was a great little car. The biggest difference between the 2 at least when you sit in them is how much wider the Focus is. That was my only complaint with the Fiesta really. It always seemed my left knee was up against the door pull. Why they put such a large door pull on the Fiesta and mounted it low is beyond me. The Fiesta cornered as good as my Focus despite having the rear beam. In some ways my Fiesta was more fun to drive than my Focus. The steering was better for one. Of course in off the line acceleration, the Focus is much quicker. The Fiesta once up to speed on the highway was fine. The Fiesta had 10 more hp than my 1986 Dodge Omni GLH. Didn't have any problems with passing and such. Between the 2, I'm glad I swapped for the Focus though. Wider inside, more cargo space, nicer interior. Gave up about 3-4 mpg overall, but I can live with it. I think some people are talking the FiST over the FoST because it feels lighter and more tossable maybe. One complaint I've heard about the FiST is that the suspension is pretty harsh. More so than the FoST. As far as price, the dealers are price gouging from what I can see with the FiST. You can get a base FoST for the same price or cheaper than a FiST right now.
