A very unreasonable reason for me not switching to Safari is because the bookmarks dropdowns (when activating the bookmark bar) have two very annoying features. Firstly they only open when clicked, so if you click one and move your mouse to another, the other doesn't open, just the original stays there and you have to click off it to close it. Secondly there's some kind of delay to that click such that if you accidentally click the wrong folder of bookmarks, click off it to the correct folder and click again to open the correct folder, if you click too fast it'll do nothing - no opening the new folder, nothing. And it'll continue to do nothing if you continue to click 'inside' the timeout window. So you have this artifical delay built into bookmark navigation that just put me off.

That and also ultra-wide tabs which change in size as you close them with a middle click, which is really annoying and you sometimes close the wrong tab. Close them with the cross and they stay the same size and neatly collapse, you can even then middle click to close the remainder and they stay the same size. Silly difference in behaviour IMO.

It's the little things that put me off. Shame, as Passkey support is great.
