There's a much more to this but in short, here's couple things...
Spool/Solid axle, both front wheels are locked, and spin together at the same time and speed, while the diff allows each wheel to spin each at different rate independent of each other. The diff will give you a bit more steering on corner entry, but the spool car can accelerate harder out of corners, and less maintanance, which is why most pros and joes run Spools for outdoor asphalt racing. Over the years racers have found out that running a front spool/solid axle is faster over all.
