Generally on a average Linux is more stable than Windows.

I use it as my personal OS for my laptop. If I use Windows, morning the laptop works faster, and by afternoon or by evening, it gets slow, and gets sloppy. This is the issue with inconsistency with Windows usually. Also besides any crashes.

So in general if you use Linux instead, if you see any inconsistencies it is due to Apps. sometimes. But your system should be perfect, even if you do not reboot for a week. So that is how stable it should be usually.

I suggest Ubuntu in general for your desktop use. Since it has more tested application updates.

Best wishes !
