Well, if you're "high mileage", then maybe you have a limited number of squats in you per session.
Or, perhaps the ballistic nature of the full range lifts bothers your knees or hips.
Or, maybe your skill level on the classical lifts are small, but you want a higher loading.
I don't think there's all that much more benefit to the full lifts than the "power" versions for the vast majority of people.
I, myself, lean towards the camp where I feel the full, classical olympic lifts, while extraordinarily cool, also take a significant time to master, and need to be considered on with a cost-to-benefit ratio.
