On paper they should be equally as quick, but realistically the blower motor would get there easier and would be a lot more fun to drive. I also think the blower motor would be quicker with a not so ideal set up (who ever has a perfectly dialed in set up). I'd go forced induction
boosted would give you a drivable/usable car, whereas 700N/A would give you a super high compression, big bumpy cam not streetable car that would require high octane, expensive high stall and most likely need steep gears to work.
