Biggest pre-flop advantage in Omaha

[slapdash]

Received wisdom is that the difference between two hands pre-flop in Omaha (high) is a lot less than in holdem. In a sense, that's not true, because, unlike in holdem, in Omaha there are dreadful hands you can have. For example, 2222 is guaranteed to lose to any hand with a pair. But what if you rule out the "dreadful" hands? Two hands that don't contain three of a kind or quads: what's the largest possible pre-flop advantage?

Re: Biggest pre-flop advantage in Omaha It's so difficult with omaha because even if we ignore the hands that contain trips or quads there are still plenty of duplicate hands. For example hands like: As Ad Js Td vs Ah Jc Ts Jd - the latter would be 12/1 shot to win the hand out-right. or even worse, something like As Ks Ah Kd vs Kh Kc Ad 7s - the first hand would be about a 95% favourite and with split possibilities there's only about a 2% chance of the latter hand winning outright. Think that is about as big as it gets.
