User blog comment:Kylie Jenner's Secret Baby/Pros and Cons of UCP/@comment-38078079-20200816095243

I like UCP overall, but I do have one major gripe (which staff blamed on my device).

On Legacy, VisualEditor seems to account for space dedicated to side-columns like "popular pages"; it's roughly the same size as the article itself, and allows for a rough preview as you go along, so you know how images will be placed, etc.

On UCP, that space is not accounted for and the editor takes up far more of the page, beyond that of the article, and - on comparing the editor to the finished article - images can be in totally different places, paragraphs can be totally different sizes, headers can be in wrong places, etc. It means (especially without a preview button) you're editing in the dark in regards to how it'll look in the finish.

If I were on UCP, I'd have to exclusively use Source, as VE just isn't up to scratch.

Maybe it is just me, but. . . yeah.
