700R4 is a street tranny. You don't need the OD on the strip and the spread between the 1-2 shift is too great for a good strip tranny. The TH350 has a better gear ratio and is lighter.
Depending on your diff gear ratio and tire size will determine what is better. You shouldn't go more than 3.73 with the TH350 if you plan on any daily driving especially at highway speeds.
