Here's the lowdown man. I've ran both of those tires and will continue to run the BFG's this upcoming season.
First of all, either one of the drag radials you listed will work fine with the stock sawblades. no worries there.
Ok, if you like to drive around a lot and are lazy about changing your tires everytime you get to the track, get the Nitto's. They are decently grippy and have very very long tread life. They need to be SMOKED to grip well though. My best e/t with the nittos was 12.44 @ 115 mph, 2.0xx 60ft. The Nittos will spin, then grip, and this helps to ease the stress on the drivetrain.
The BFG's are much grippier and have a lot less treadlife. You can't drive around all day with them the way u can with the nitto's. Properly heated up, these things grip like a mofo. Dump the clutch and you WILL bog. Trust me. These things are so grippy I had to totally re-learn how to launch the supe. Definitely upped my game once I learned how to used these babies. Best time on these were 12.06 @ 115mph with 1.800 60ft. Only bad thing about these DR's is that I've broken two trannies with them. wayy too fookin grippy mate. With an auto this shouldn't be as big of an issue though.
I'm pretty fookin lazy and I hate changing tires back and forth. So in the real world of street racing, daily driving, and drag racing, the Nitto's would be the best bet. If you're hardcore and putting money on a drag race, u better be packing the BFG's though

. I fall into the latter category
