Where it's feasible. Having an abnormal number of home devices lets me have my cake and eat it. As Grungie points out the transition is not an easy switch, the Linux way is fundamentally different and while people with generally little knowledge of the difference or people who are just that in depth may not find it challenging, there is a vast in between of hurdles that cause people to skip a beat and swap back.
If anyone is thinking of this, the best advice I know of is to measure your expectations, to avoid jumping right into the deep end, and to not overthink it. Pick something and run, I tend to think Linux Mint is the best for this but if your spice is Debian or Ubuntu or heck, you're that odd fellow who got right into Arch Linux and loves it, then stick to it. Hopping is an easy way to kill your momentum, most of what you're looking at is just the desktop (not the same as the wider OS). Maybe instead decide if you like Gnome or KDE or want something in between (Cinnamon is a nice uncontroversial choice, XFCE is great for very low end hardware), and pick the best distro that appeals to that. For all the difference there is a great deal that is the same. Bothering with all the this or that is what knocks you out when most setups are just fine as long as they suit your hardware.
