Which have you been using/ toying with? To what results? Please share your experiences as I intend to take the plunge, after 6 years of VMs and speculating now it is the time, I guess.
I recommend either Ubuntu LTS or OpenSUSE Leap. A long term service support distro is your best bet. Not too radical and comfortable in day to day use. I replaced rolling FF with FF ESR. I don't want to upgrade my browser anymore than I want to upgrade a distro every 6 months or so.
Elementary OS 0.4 Loki (just released, based on Ubuntu LTS 16.04) http://blog.elementary.io/post/147637979911/loki-04-stable-release http://betanews.com/2016/09/09/elementary-os-04-loki-ubuntu-linux-stable/ https://www.youtube.com/watch?v=RArSh5uYEpY
