I can't compare them, but I just received a book from Blurb and was quite happy with the quality,
Generally, me too, & I've done two different sized Blurb books.
The only thing I don't care for is the somewhat limited options for page formatting, but its nothing that can't be worked around with a full page image that actually has the formatting/contents desired.
That was my solution, too, & don't think Word is all that easy to work with exact image placement. PS did the job very well. The only thing you have to watch for is the binder & outside trim margins.
