For one thing Kabuto's SM is similar to jiraiya since he enters imperfect Sage transformation(the only person with perfect sage transformation was mitsuki) Orochimaaru is also not perfect SM user since he never found that ideal body though maybe with WZ 's body he could perhaps enter it. And being perfect user needn't give any advantage. For instance Jiraiya could increase his mobility using Frog jumps and(warning speculation) breathe under water like frogs through skin. Similarly Kabuto has significant advantage during battle as we saw him take on both sasuke and itachi without tiring. Proper balancing only ensures that one retains his features.
