I'm wary of people who claim to be putting out an "ultimate" anything (their "ultimate" RWS and Thoth books, which were roundly criticized here), so I would be skeptical on that basis alone. Nearly all of the few US Amazon reviews were one and two stars, mainly for the size, the cardstock quality and the misleading advertising (although I think some people may have been making assumptions). Besides, I don't even like the two extra Magus cards; there's a reason they didn't make the original cut, and, according to the first edition with them included, they were just a bonus, never intended to be used as extra cards in readings.
