1. ios performance in scrolling and loading (especially on my ipad pro m2) is unbearably slow, just stutters everywhere when loading a page in the background
2. tap-and-hold to open a link menu is so strange; sometimes it highlights text instead of showing the menu, sometimes it works ok, there is some kind of strange ui timing issue at work
3. on ipad and ios the tab overview display scrolling is absolutely appalling like 4fps level slow... completely unbearable to scroll through tab previews
4. developer tools are abysmal compared to chrome
5. on desktop performance is also extremely slow compared to chrome, its night and day
6. battery usage is so bad on ipad, just leaving some tabs open they run down the battery and chug memory (i know this is more a web thing, but they should at least freeze tabs in the background or make it an option)
7. just strange bugs on ipad, when tapping a text field the keyboard pops up, then suddenly disappears and the pops up again... just a terrible app
etc etc lots of paper cuts, but the performance issues are the biggest for me... i like the tab groups + auto save and icloud sync and built-in spellcheck, but its getting harder and harder to resist the alternatives
