that are actually the small little things which are fast on a Mac. This seconds of thought are also clearly visible on some Ubuntu machines... Gnome is not always optimized and Snap programs make you think your laptop is frozen.
i3 isn't even snappy, the default application launcher can take up to 10 seconds to open on my old laptop.
There is a faster application launcher you can use instead, but you have to hunt through github issues to find out about it. The i3 project maintainers seem to actively object to telling users about 3rd party components and simultaneously refuse to integrate them or improve the default behaviour.

Of course, the problem is often that with other options some assembly is probably required. But looking at the mess gnome extensions are, that might actually be not that much of a difference.
I'm a heavy Ubuntu and Mac user, and wake from sleep is much quicker on Mac (as in it wakes before I open the lid completely).
Multiple Macs, multiple Ubuntu machines (although I've given up trying to get a perfect Ubuntu laptop, so that's desktop only these days)
