If you have lots of tire spin, your 0-60 time is not gonna be quick, regardless of what rear gear you have. Back when I raced my '69 GTO with hard street legal tires, I popped the clutch at about 3000 rpm, but i couldn't go to full WOT until just before the tires quit spinning. If I went to WOT any sooner, the tires would just keep spinning for quite a while longer, resulting in a much slower ET.
With a numerically low rear gear, if the tires don't spin much, but rather hook up at low rpm, it might actually "bog" the engine down, til the rpm get up into near the peak torque range. The bog will be worse, if the cam does not provide much low rpm torque. So, the trick is to get just the right amount of tire spin, but not too much, & going to full WOT at exactly the right time.
With the engine in it's peak torque range, and the tires hooked up, acceleration will obviously be better with a numerically higher rear ratio. And, as for the extra shift, with a little practice, the shift only takes a small fraction of second. So, the numerically higher rear gear ratio will more than make up for anything lost to the extra shift
