If you intend to charge the batteries and intend to use it immediately Energizers will be fine for your needs. They have higher Mah's compared to Eneloops, so it will give you longer runtime. However if you charge and don't intend to use the battery immediately or only use it for short runtime over weeks and months, then Eneloop will be much better. The fact they hold their charge means they will be there when you need it.
Assuming water is energy in the battery, think of Energizer as a bucket full of water with a small hole in the bottom, where there is a constant and steady flow of liquid draining out of the bucket, if you drink quickly enough, then you will consume most of the water in the bucket. However if you drink slowly you will not be able to drink all the water that was originally in the bucket, because some of the water has drained away.
Think of Eneloop as a smaller bucket full of water, but with a pin prick hole in the bottom, the flow of liquid draining out of the bucket will be lesser due to a tinier hole. If you drink quickly, you will consume most of the water in the bucket, but would still less than the Energizer, due to a smaller size bucket holding less water. However if you drink slowly, it does not matter as much, because you are not losing as much water over time.
So the decision to choose Energizer of Eneloop depends if you are a fast drinker or slow drinker!.
