Maleic anhydride or Itaconic anhydride for amino group protection?

I want to reversibly protect an amino group in a quite sensitive
molecule, in a reaction in the gram scale. I came across maleic
anhydride and itaconic (methylmaleic) anhydride. Any ideas which one
is more convenient to use (and to get rid of)? Is there a major
difference between them, actually? Both are introduced in alkaline
conditions (pH 9) and removed with a not too acidic buffer (pH 3)
Many thanks for your suggestions!
