If you've been playing for as long as I have most magic items are boring. That's why as said, I homebrew and concocts many on my own. Keeps both my players and I excited and never knowing what to expect. Core magic items are simple staple fodder to through into a treasure horde.
To spice up magic you can always add a drawback (i.e. every time used you temporarily lose 1 ability point). Makes players have to decide on whether they should use it or not. This should be a rare thing, but it is fun if used very sparingly.
Make weapons with lore and history. Who held it previously? Make it intelligent! That leads to all sorts of great role playing!
