The fact that you don't have to load the system with bloatware and third party apps to make sure that your system is secure, nowadays #linux is also target by virus and malware but generally speaking I still feel more secure in linux sticking with official distro packages and flapacks. I started trying out immutable linux distros, #universalblue aurora being a good example, this in my opinion, is a very good way forward for linux desktop. Cheers
