Acacia is a different soluble fiber than Benefiber (which is guar gum) and FiberChoice (which is inulin). Both of those are a lot more likely to cause gas and bloating than the Acacia (especially the inulin). The Acacia is organic and is not processed. Benefiber is hydrolized and not organic, FiberChoice has added flavors/colors and binders and is not organic.
The fiber dosages for all three are pretty comparable. Acacia has 4.5 grams soluble fiber per tablespoon and the others are close.
Acacia has a prebiotic effect in the gut - that means that it encourages the growth of probiotics (healthy gut flora). So it can end up reducing gas and bloating if you're regularly taking it. Guar gum and inulin won't do this.
