Same awesome style, but everything else is simply not the same. Armand is not Lestat.
And besides that, I never liked Armand, at all! From what I got from here, as a human he wasn't half bad, but as a vampire... Power corrupts, and so does the desire to survive, whatever the cost.

Spoiler

Two things bothered me about the writing though:
1. Armand saying that Lestat fixed his eyes on them when telling them about his journey through Heaven and Hell, when he only had one eye at the time.
2. Marius making two new vampires apparently in a single day. From her other books I gathered that a vampire cand make a powerful offspring only once per century, and Lestat's blunders were enough proof of that. Not to mention that Marius actually took two days to fully make Armand, Amadeo at the time, so it's not his style to make two in one day even if he could.
