gallo nucleus 3.1 vs. vandersteen sig 3a

there are a lot of threads about the attributes of both, but nothing head to head. i have a geriatric pair of vandersteen 2ci's that i have loved and cherished for well over a decade plus. but, it's time to move on. initially i was going to go straight to sig 3a's. i love the vandy sound and have found richard vandersteen to be entertaining and informative to talk to over the years; a guy i like to support. however, the used price of the gallo is such that i am tempted. the new price for the 3a vs the 3.5 is roughly the same as well. what say ye?
