The top is definitely the best. The other two are cluttered and distracting. I'd polish it. The font is okay. I like the curves and subtlety, but I think it's overly understated and simple. It's more readable and less compressed than the current. The disproportionate and different font f is jarring and detracts from the symmetry of the rest of the logo. It delineates the word separation so that the random person isn't reading "stylefor" well, though. Edit: Looking at it, you might do well if you resized the f on the first and offset it as in the third, but without the effects.
