I like the middle piece style and I think others do too. It's just the 'D' logo some people don't like.
But, if I understood the start post right, the D is just an optional logo and not a part of the case. It's really complaining about nothing at this moment. It's like "the PCB has LED support but I don't even use those... badly designed product".
I think branding, to some point at least, is very important. If you look at the currently available TKLs you quickly realize why that is the case: They all look alike. Even if the logo would be forced for some reason, I don't really see a problem with it as long as you can choose the color of it. A nice grey to grey contrast (or going for no contrast at all) can really change the looks of it and will take away the flashyness, if that's what you prefer.
