Not counting the time a lady popped her clutch pulling out of her driveway and hit me, since I guess that’s not “almost” an accident, probably the time I got caught out by a snowstorm, and on the way home I did a 360 on the freeway before regaining control. Thankfully there was no one else around, so it didn’t hurt anything other than my pride.
If you think China is any better than the US, then you’ve just switched flavors.
Honestly, unless there’s some specific thing you’re looking for just use your distro’s default. If your distro doesn’t have a default I’d probably default to ext4. The way most people use their computers there’s really no noticeable advantage to any of the others, so there’s no reason not to stick with old reliable. If you like to fiddle with things just to see what they can do or have unusual requirements then btrfs or zfs could be worth looking into, but if you have to ask it probably doesn’t matter.
Mint is actually really good about not having weird dependency chains, and even if it did uninstalling apps would warn you about it. That is a very strange thing for people to have said. It is perfectly normal and good to have some things you don’t want or prefer an alternative to and uninstall them. Default Mint is a great sane starting point for a complete OS, and I think their updater is the best in the entire Linux world, but it’s still Linux. You can still customize it to your heart’s content. Anyone who says otherwise is just being a creep.
