Problems for me:
 * No search bar or link to userpage (except in the ugly view).
 * Both editors are basically just pop-ups and like you said, way buggier than the original editors.
 * The editors which the new version uses aren't even supported by the Browser I use (mobile Chrome). The old editor is and works perfectly fine for the most part, the only really buggy thing that comes to mind being adding a new category. (Yet, ironically, it is that editor which FANDOM considers buggy.)
 * Typing in the new editor makes the text bounce back and forth so half of the time I can't even see when I'm typing.
 * Selecting text is basically impossible.
 * It automatically added two empty rows after a thing I typed and I have no idea how to get rid of them and now the page which I edited looks ugly because of those two extra rows.
 * There are only three rows of visible text when the keyboard is activated (compared to 17 in the old Source Editor). And yet the Classic Editor still manages to have more useful stuff visible at once.
 * Highlights no longer highlight the entire bold/italic text, making it hard to see what is part of it and what isn't. Only the marks themselves appear different, but you can't distinguish starting and ending.

And the thing is, FANDOM isn't even the first website I use regularly to ruin itself with a major change that everyone dislikes in 2020.
