It's a big quality of life feat for me. The extra slot is really nice since I always take throwing, and the ability switch something out without using your whole turn is very nice.
I wear utility belts and my standard loadout is nets/caltrops/frag/incendiary/taser, switching out for HE's/flash/Emp/Toxic as needed. There are always times when you realize something else would be better, like a different gun or different kind of grenade, and then there are times when you use all of your ammo or a whole stack of a utility and need something else.
