It is not necessarily that any one cleaner is better than the other. I assure that whenever you use a different cleaner, it will more than likely find something that the other left behind. CCleaner is my favorite, and it's all that I use, but run it, and then try running Wise Cleaner 3, and you'll see what I mean. The reason I like CCleaner is because it is safe, and for the most part, complete. but no program is perfect
