I do agree that most of the detail gets lost. At least for me when the icon is smaller than 30x30~. I personally dislike the the simplification of the new icon makes it feel like it lacks any personality. I specifically miss the globe more then anything else. The globe made it feel like a web browser too me without it I wouldn’t even known what it was the first time I saw it.
At less for me the newer two logos makes it feel more like a brand then a piece of software with a cute avatar.
I don’t know how how to express my feeling and reasoning for my feeling into words.
If you’re the kind of person that gets demotivated really easily when there’s an opportunity to crawl back than I would wait until EOL so you feel more commit it to your choice.
Though the reasoning for my mind set is because I install linux 4~ times before I really committed to using it as my daily driver. The final push was two very big bugs.
I still have windows installed but its only to play rainbow with some friends.
