I've tried them but far prefer running triple-head setups (since the days of Xfree and CRTs). Triple-head is pretty easy these days and gives you one central monitor plus one either side to chuck windows onto. Current set-up is 3xDell U2715H for a total of (2560*3)x1440 (and 10 workspaces). If you are going wide, consider vertical resolution/vertical size as well (to minimise swivelling side to side).
