I just let it depend on the situation.
Raidboss lvl >78 means I share with allies, especially when I have no raidpoint to spend for the next half hour anyway, meaning I have less use for spawning another.
When there's a raidboss scarcety (like an event which spawns no raidbosses), then I'll share most raidbosses with allies only, so as many people as possible can tag it for their daily.
When there's a raidboss surplus (sometimes happens during the first days of an event where the event currency is dropped by raidbosses), I tend to share more raidbosses with public instead.
