Considering that oxyclean is absolutely perfect at removing labels, it's really not possible to be better, let alone MUCH better. That statement makes me pretty confident you've never used the stuff and just pulled the comparison out of your ass... but of course, this being the Internet and all, you're bound to insist the contrary either way.
Now, it may very well be JUST AS perfect as Oxyclean, and it does has that price advantage. But oxyclean is so useful in the brewery *beyond label removal* as a VERY effective cleaning agent, that everyone should have it on hand anyways. And using it to soak bottles provides the added benefit breaking up any sanitation-interfering crud or oils that you might not get with a bottle washer/brush, or even know is left behind.
