Yeah, that YT-2400 has a Class 2.0 Hyperdrive, and a Class 12 backup.
The Falcon has a Class .05 Hyperdrive(Fastest you can get is .01, with .00 being infinite speed), and a Class 10 backup.
Plus it's got heavily modified weapons, internal systems, smuggling compartments, stealth capabilities, etc...
It might look like a piece of crap, and breakdown more times than Han can count, but that's one helluva ship.
