To me this layout (dark style) seems more roomy. The info under the avatar is more spaced out I think. It makes most posts bigger but I think it's easier for old man eyes to read.
I think there is still a few options that could be done with some of the colour selections but that could also be old man eyes so I'll just change them locally on my screen and be done with it.
I also had to force Firefox back into using the proper English instead of telling me words like colour were always spelt wrong, but that's a minor issue that no doubt changed with a cache flush of the old site.
