Depends on what features you mean, but I think that ROM is "stock" to the people who are seeking it. Otherwise, you can put a different launcher and change the home-screen appearance of any ROM, including Nova Launcher, Apex Launcher or even the Google Experience (or Google Now) Launcher. Otherwise, several ROMs, Paranoid Android and others, do push innovative ideas into their builds, but I'm not aware of any specific ROMs that retain most of the TouchWiz enhancements without the bloat - mainly because the enhancements are made out of the same stuff the bloat is, from a coding ecosystem perspective.
In my opinion:
The benefit of Stock isn't purely aesthetic, it lies heavily in not having all of the extra bloat and heaviness that comes with the absence of needless/poorly implemented ideas. Some of HTC and LG and Samsung's, etc ideas are really great and I can easily see the use case for many of them, but the obvious most "ideal" mix of software additions is the Motorola execution (in the Moto X, Moto G and Droid 2013 lines), where useful features and apps are added - as apps - to a mostly stock-like environment.
There are no obstacles stopping the other OEM's from doing the same thing or taking a similar approach, however they choose to add these things as unified approaches either due to coding laziness (which creates more complicated re-work later) or because the visual design cues are easily identifiable by consumers and provide differentiation. So to me, the "super ROM" already exists, and it's free - it comes with the Moto X. The other features I might like to play with, mutli-window specifically, would be neat, but no one has implemented them in a manner that makes them overly useful (they need to work with any app, not a white-list and work outside of a TouchWiz environment). Etc, etc.
