The difference in power is a complete wash between dyno variance. You're sweating over maybe 1-3hp, which would never be felt.
That said, I imagine the Admin pieces would fair best if you have ported TBs and upper/lower manifolds, otherwise those stock components would inhibit the full benefits of the larger pipe ID intakes. Also probably worth saying that although Admin is pretty pricy, a lot of people here have raised questions about quality/fitment of AAM parts.
