What's the difference you ask?
Basically they're the same with one exception, the bact water has benzyl alcohol as a preservative. This means the liquid will have a longer shelf life.
The downside?...If you have a product that gets damaged by ba, you'll want to stick with the sterile water.
Conclusion: in a pinch they both accomplish the same. If you plan on using the liquid up fairly quickly, it won't matter which one you use. If you think its going to be a while and you're certain the ba won't harm the active ingredient, go with the bact water.
