Elementary OS 6 discussion on reddit: https://www.reddit.com/r/elementaryos/comments/hyz8yk/elementaryos_6_all_you_need_to_know/
Elementary is nice looking and well put together but I don't like how they brush off a11y and i18n stuff in there.
Also TBH min-max-close and drop-down menus are time tested, proven, or at least widely familiar UI. Departing from that is a gamble with terrible odds.
Some say it's Mac influence but that OS has a menu bar constantly present, and the header bar is just an additional toolbar.
