Query: either System is Super, but both? not so much

Bought Super I & II because I was told there were major updates in II. That is simply not the case, at least for the No-Limit Hold-Em chapter, which, let's face it, is why most people (myself included) buy these books in the first place. I'm not knocking the books themselves, far from it, there's very good knowledge in both, but it is largely duplicative. So, my free advice is buy I or II, but not both. (If pressed, I'd pick II.)
