the entire package
I agree, of course.
IMHO the 700 is the better choice for your project for the reasons you mentioned, especially torque capacity and 1st gear ratio.
Although both will handle any power a mild or warm L6 will produce with only a good selection of parts (typically from Corvette, V8, diesel etc. as to clutch pack), if you anticipate major mods in future the 200's safety margin gets thin and it's cheaper to start with the 700.
One range where the 200 has an advantage is where the original axle is numerically high (3.73), so the lower 200 1st gear is harmless and its steeper OD (.67 vs. .70) is helpful.
The reverse: a vehicle with a very tall axle (3.00) will need as much 1st gear as possible, and less OD so the 700 wins here.
More input, more data, more discussion = better choices.
