I think that weapons that do something are far more interesting that a weapon with a +. In the flame tongue thread, I mentioned that I would choose a +0 flame tongue over a +2 sword just because a sword which bursts into flame is far more interesting that a sword that just has a +2 bonus.
I would suggest (and I think I may do this in my games now that I've thought about it) looking at 3e for ideas. They had all of these different weapon affixes (bane, holy, flaming, etc) that you could probably use instead of a straight + to a weapon. In addition to those, allowing a weapon or armour to provide some sort of spell like effect or special would also be cool. If I was a stealthy rogue, I think I'd prefer a suit of shadowed leather armour that grants advantage on stealth checks in shadowy conditions than +1 leather armour. Again from the flame tongue thread, having a magical sword that can surround itself in phantom flames that sheds light like a light spell would mean that your human warrior no longer has to worry about carrying around a torch when in a dungeon. Perhaps the sword can also expend these flames to surround an opponent with a faerie fire effect once/day. items like this are interesting and memorable instead of being just another +1 longsword. You might even find that the player with the sword that lights up keeps it instead of taking up a +1 magical longsword that shows up later in the game.
