I like thele´s items because they are so different.
I like the idea of cursed but helpful items. I played the pool of radiance PC game and in that game are several items which grants your PC some bonus but some items also give in combination with the bonus some penalty.
I like items with level progession. I´m a big fan of the magic items in Earthdawn.
Who remembers a magical "normal" sword after reading the text about a sword with some special abilties (without a unique history of the item), but I will always remember your creations because they have (unique) flavor.
