Car problems??? and which is better izuzu or jeep?

My brother picked up 2 cars from an auction, he already has a new truck so he said i could keep one if i wanted. Im having a hard time deciding which one to keep, I dont know much about cars. The first is a 96 grand jeep cherokee and the second is a 98 isuzu rodeo. Both only have 2 problems, and other than that are in excellent condition. Something is wrong with the 4 wheel drive in the isuzu and something is wrong with the altenator in the jeep. Im not quite sure what on both, i have an appt to get both looked at on monday. Which of these cars do u think sounds better?
