We got the 14:1 upgrade kit for our Toughboxes, and... wow... that had to be our best performing drivetrain EVER. (2CIMs per side, through 14:1 toughbox, direct to 6"x1.5" IFI traction wheels with roughtop).
I think I'd go with the slower, quicker robot again, even in an open field competition. Robots tend to spend more time maneuvering than driving in a long straight line.
It will change from game to game, of course... but what good is a theoretical top speed that you never reach?

We chose to make our robot so small this year we ended up with both.
At 106lbs with 4 cims and 2 toughboxes chained to 6 plaction and 4 2008 kit wheels it maxed out around 13fps and accelerated to full speed in roughly 15 feet. As a bonus we could push pretty well too
It sure was a shock to all of us how our drivetrain performed this year, I will say it's the best one we have ever made.
