Well, it would take Voyager about 70 years at maximum warp to travel from the delta quadrant back home. Apparently Han can fly to the other side of the galaxy far far away almost instantly. I don't know how fast the light travels in the Star Wars universe or how big the galaxies are but I would say the Millenium Falcon is way faster than any Star Trek vessel. But ofcourse a Borg transwarp hub is a faster way to travel but it's not nearly is practical as the Millenium Flacon.
