As noted many times, GFS has sucked all winter especially with southern stream snow threats, but I thought it did pretty well over quite a long lead time with the general timing and placement of the March 5th severe event as well as the one coming up for this Friday (although obviously not good for crucial details like 0-3KM cape that are critical for event magnitude). Of course, I wasn't really comparing it to the Euro or other models, so it's possible they did equally well, or better.
