Nah, I stick with Nikon batteries. I just look for the least expensive price. I even have an EL-EN 15 Watson battery that I got as part of a camera promotion that's still in the blister pack.
You can scrimp on some other stuff but for things like batteries and memory cards, it's better to buy the best you can afford. At least in my opinion.

I got one of those Watson batteries with my D7100 and it won't even light the charger up. (Interpretation: it doesn't even pretend to start charging - it's totally defective.)
UPDATE: The good news part of this short tale is that I called B&H about the useless (free) battery they included in my order and they let me return it and gave me $10 off a new Nikon EN-EL15, so I'll have a good spare.
