Yes, it does a bit. 200 has lower final (0.67 to 0.70) and 700 has steeper 1st (3.06 vs. 2.74), 200 has better “spacing†between gears. Ultimately, I let no computer and less mods dictate choice. Either generally can be made to handle horsepowers involved.
Availability of Trans is also an issue. I hear the 200s are getting harder to find.
