My opinion is worth not much. But i've shot iron sights competitively for 15+ years. I know them well. I can still get to the target quicker with a low power scope and break a good shot. Thats may only be me though. FWIW I can shoot faster with irons just from pure speeed but the accuracy is not there. I have a tendancy to just see any part of the target and start pulling, where with a scope I can tell where I'm at for sure.

If I were going peeps I'd go the above mentioned route and use a williams type setup where I could zero in with the peep in, carry it out for close range and screw it in for long range.
