Dual Plane vs Single Plane Manifold with TBI

Wondering if there are any advantages or disadvantages to using a dual plane intake (such as the LD4B) over a single plane intake such as a stock 66/67 Commando when using a TBI such as the Sniper/FiTech? I have both manifolds and see the TBI will bolt right up to the LD4B. If using the Commando, an adapter is required. Would like to see Any and all comments from the guys and gals in the know on this subject
