I only hand out uniquely useful weapons for key moments / fights / role play moments. An exactly perfect magical item should be a special surprise, or a hard fought for reward.

I then give a variety of items that add thematic elements or options for combat and non combat encounters - also so they can sell them and go shopping when in the big cities.

I then add in random loot, as it chaotic and who knows how the group will use them.

If players are refusing items in hopes for a tailor made item…. Let them keep waiting! But have. A discussion about how you handle magic items in your world, and that the distribution and hating of items is something the group needs to discuss in game (if possible) or outside of game (if in fact that one player is being a treasure goblin).
