Some Good info.
I would not worry to much about the difference in first gear ratio for making the choice, either will work fine in a 3.73 driver, just my opinion having had a 4l60 and 3.73 and 4.10 gears.

I would see what is the easiest to swap for you, for example the 200R4 is shorter than the 700R4 by about 3 inches (its a direct swap for a TH350) so maybe driveshaft will not need shortened, not sure, just an example.

Both trans are good, either can be made quite strong. I would think building and parts prices might favor the 700R4. I would not hesitate to use a 200R4 though.
