Shandera:
x0: Normal, Fighting
x0.25: Bug
x0.5: Fire, Grass, Ice, Poison, Steel
x1: Electric, Flying, Psychic, Dragon
x2: Water, Ground, Rock, Ghost, Dark
Starmie:
x0.5: Fire, Water, Ice, Fighting, Psychic, Steel
x1: Normal, Poison, Ground, Flying, Rock, Dragon
x2: Electric, Grass, Bug, Ghost, Dark
I bolded type resistances they do not share, italicized weaknesses they do not share, and underlined important weaknesses (lol).
In general Starmie's typing is better defensively. However, its offensive typing leaves a lot to be desired, as it doesn't really rely on Psychic to hit much of anything, whereas both of Shandera's stabs are even more hard-hitting and cover each other decently well.
Considering Shandera's role, we shouldn't really think about more than its switch-in bulk, as it won't need to really come in more than once or twice before it's served its purpose.
