The "Smart" choice would be SL1. It's a Canon DSLR and therefore compatible with all the lenses, flashes etc. The AF will work better than mirrorless options and the camera should be a lot more responsive.
Personally, I've recently picked up a Fuji X-E1. I love the styling and layout with direct access to controls (with the exception of the AF selection button). I'm very impressed with the image quality, I love the lenses and the camera has many very cool features. I'm really happy with my choice. I'm also impressed with the Fuji philosophy, in which they release frequent firmware updates to improve their cameras rather than release new models and "force" people to upgrade. There is also a lens roadmap (which they have largely stuck to), so you know how the system will evolve over time. Its small things like this which make me feel positive about them as a company. They seem to be listening to their customers a lot more than some other brands and delivering products for people that love to take photos. I'm really excited by the AF improvements on the x100s. When those improvements make it onto future X-E1s and X-Pro1s, I think they will become a serious option for many people. If they can couple that with semi-acceptable AF tracking, for me, that might mean bye-bye DSLR time.
But there are some negatives which stop me from recommending it to others. Firstly, while their lenses are good, current options are limited (and while you can use adapters for non-fuji lenses, you are left with manual focus). The AF isn't "bad" but think more P&S than DSLR (In its favour, it does have a very wide spread of focus points and when it does lock, it is generally accurate). I'm getting about 400 shots per battery, which isn't fantastic (but then the SL1 is only rated at 380). While the flash sych speed is meant to be 1/180s...you can't actually set the camera to this in most modes - typically, you are at 1/125s and there's no high speed synch. You're stuck with the rear LCD or the EVF. While it can take videos, it isn't really geared up for serious video use. And while the EVF is occasionally useful for adding extra information, most people would prefer an OVF. And lastly Fujix-rumors is nowhere near as entertaining or informative as canonrumors. For me, the negatives weren't major problems and were countered by some improvements over Canon (such as significantly better infrared capabilities). But your needs might be different - just make sure you make an informed choice.
