I think it really comes down to your goals and hiking style.
If you're going to be hiking all day for long miles, you won't be sitting around much anyway. You'd be better off cutting weight so you'll be more comfortable while you're hiking. The best way to cut weight isn't to buy lighter gear, but to leave stuff behind.
If, however, you're generally taking a more relaxed pace and will be spending more time in camp, one pound isn't going to be too burdensome for some extra camp comfort.
