Yes, since the v2 case, the v4 case is proberbly the worst one.
If its a huge difference, well, that's up to the beholder
But to sum it up, every single line on the Noob case is off. The gen is sharper in the lines, sleeker around the lugs, and proberbly the biggest error on the v4 case, is the lack of asymmetrisk lug sides (right side needs to be slimmer then the left side)
Its proberbly not something you will notice a lot, unless you put it next to the gen, then its pretty obvious.
I did a comparison here of different build and my gen
