The headband is great early on, but there are too many more interesting options for it to be a long term slot. I did play a low INT wizard once to abuse it (before it was nerfed) and it was fun, but tying up a head slot isn't worth it to me.
Between class abilities and how malleable stats are in 5e, stat items are different from BG 1-2, you weren't playing correctly if you didn't build characters around the loot you got.
Just bringing this up quick, but what are some good helmets? So far the only one I've found that seems to be any good is that circlet of fire thing.
