I'd like to throw in my experience with Linux here. My backround is that I used Windows 2000 and XP from 2001 to 2003 after that Linux for three years and then OS X until 2013, now back on Linux.
I bought a used ThinkPad because I heard that that is the hardware which would work best with Linux now and I installed Ubuntu on it. Everything worked ok but just the OS filled up half of my small 128 GB SSD and running only Firefox for browsing got up the load to over 0.5, which made everything not so snappy.
A couple of months ago I moved to archlinux with Gnome 3.x, it was a bit more complicated to install, that I admit, but it was so worth it! After installation the system used less then 3 GB of my SSD, and now running just firefox the load is on about 0.01 which makes this ThinkPad from 2010 one of the snappiest computers I ever used. All animations are smooth, not a single application ever crashed or hanged itself and so on. But yeah admitedly I mostly only do development, email and websurfing on it.
