PLO vs NLHE Tournys

[CruNKinTILT]

I've basically only played NLHE tournies up to this point and felt that o/8, stud, and LHE tournies don't give good players even close to as large of an edge as NLHE does. How does PLO rank compared to other types of tournies? Let's just take the DS structure at FT - 3000 starting chips with 15/30 blinds. How big of an edge does a good player have over a weak player when PLO is compared with NLHE in the same structure.
