    Cat 345 vs deere 450

    I'm looking at getting a CAT 345B II or a deere 450c lc. Cat has 13k hrs and deere has 15k and are the same price. Which one is better? What do I look for in these machines? I'm used to deere equipment but I think I like a cat. It's going to be used in a pit for moving overburden and loading trucks.
