Nice link. My opinion:
I actually think many, if not most, of the touchwiz menus and colors look better than stock options. The settings menu, for one, in touchwiz is fantastic. Color coded, organized and simple. It's just easier on the eyes making things eaiser to find and quicker to get to. Plus, with stock you no longer get the 6 or so "quick settings" at the top of the settings menu (fully customizable, of course!) Like you do in touchwiz. Likewise, I find touchwiz's pull down notification shade to be cleaner and easier to use, too. You get faster access to the quick toggles (vs having to pull down twice. That annoys me so much on stock lollipop. Goes against the idea of "quick"), and you get to customize what toggles go where. Secondary toggles go to a second page, too. So you get more and you get the main ones quicker.
Ditto a few other things like the dialer and such. I think touchwiz aesthetically looks and makes more sense than stock in many areas.
Well, except for those gawd awful touchwiz app icons. They truly are hideous. Stock Android icons win in this regard.
As for me, I use Google now launcher and this app called icon changer (free) along with the moonshine icon pack (also free). This allows me to keep the things I like about touchwiz while still functioning almost like stock.
Just my two cents.
