What kind of riding do you plan on doing? The Coda Sport is closer to a road bike with both it's frame and gearing. It has a road crankset (52/42/30) with a MTB cassette which will give you very low gears for most roads. The Trek I believe can take wider tires and has a touring crankset which has even lower gears when paired with a MTB cassette allowing you to throw in some more serious offroad adventures as well.
For a longer commute (10+ miles), I'd go with the Coda Sport. Anything shorter and it's a toss up.
