F.I. Tech or Holley sniper. Opinions from users.

Has anyone seen a comparison of the ProFlow 4 port injection system vs the TBI types like the Sniper? I'm curious how much/what the port injection brings to the table for the additional cost. I'm thinking the current small block one. You could run the same PF4 intake and mount the Sniper on it for an apples to apples comparison. I'm going to do it down the road and I like the idea of port injection but only if there is an obvious benefit for my use.
