I switched to Ubuntu a few years ago and haven't looked back. Privacy at last, secure, no bloat.
It's not perfect, but it's used widely enough that in case you encounter a problem, there usually is a solution available online.
My system is dual boot, I actually have an installation of Windows alongside Ubuntu in case I absolutely need to use some software that doesn't work under Wine, but I rarely ever need it. The last time I fired up Windows was last summer.
