Choosing a horse

I could use a little advice.  I have two horses but can't make up my mind which one to train for endurance. They are both quarter horse mix, Ranger is about 15 hands, very laid back and easy to handle but also very slow and has a rough trot.  He's 10 yrs old.  Joe Joe is 13, just over 14 hands and a go-getter, much higher strung, I constantly have to hold him back and he has very slow brakes at a full gallop. I have been advised that Ranger will probably become more energetic with training and that his temperament is more suited for this sport.  I feel like I can work with both of them for about two more weeks before my time will be eaten up as we move to more strenous workouts.  

Thanks for any comments
