Although you're very unlikely to find anyone who just happens to have tried both these specific makes/models, I can at least offer an informed speculation that either choice would be a very, very good one.
I own two instruments with the SGD N3s (soapbar form), and love them for their deep, phat, thick, yet clear, modern whoomp
! From what I've read about the Delano (from two other users who have posted their impressions), that one should also deliver "deep, phat, thick, yet clear, modern whoomp
", but perhaps sound a bit less refined than the SGDs, with a little more aggressive, MusicMan-style punch - as per the huge, 9.5mm pole pieces. For that reason, I'd bet that the Delano would be just devastating for playing hard rock or metal.
