Wholly disagree. MS loves to redesign their UI, but does it half-heartedly. There are dialogs that have had things moved to the ribbon or sidebar or property panel, but only some fields, so the sidebar contents are incomplete and you still have to find where they "hid your cheese." For simple tasks like writing a memo, it's fine. But as soon as the task is non-trivial (like changing default styles in word, or making a scatter plot line graph with column a as the y axis), office is a terrible user experience for new users, and guaranteed frustration from previously-proficient prior users. It's click-something-shit-not-that-undo whack-a-mole.
