For a 5-10 mile run, I would say that the plastic bottle is the best. Whether you carry it in your hand or on a waist-mounted bottle carrier is up to you, both have pros and cons. The bottle carriers can jerk up and down, and getting the bottle in and out can be a pain. Carrying in your hand can make your arm/shoulder tense up and can be uncomfortable.
I'd stay clear of camelbaks and the like for runs of less than 2 hours for comfort and practicality reasons.
