I don't have any experience with Lulu, but I can tell you I have been completely pleased with Createspace. I bought a package deal that included cover design, interior design and a round of editing. I spent quite a lot on it but felt like for my first book I just couldn't learn quickly enough how to do the design functions well, and I had read in several places that I would not be able to edit for myself and should invest in an outside professional opinion. I actually used 2 editors, the first was someone I found on the internet and the second round was the Createspace assigned editor.
I was completely thrilled with the cover and interior designs. I felt like they both captured the message of my book and reinforced it well.
The editor from Createspace gave me some opinions that conflicted with my first round of editing, but they were professional and well considered. I used most of her suggestions and just ignored the things that I felt were in conflict with the first round when I liked that viewpoint better. She had some great ideas that my first editor had not proposed, so I felt like the combination of the two was balanced and well worth the expense.
I can't speak to how the distribution might differ between the two. I have taken advantage of the author pages offered by Createspace for free in the UK, France, and Germany but have so far not seen any sales in any of those 3 regions. I have just received my third shipment of books to sell myself and can tell you that the quality has been great. Out of 130 books so far I only received 1 which had a problem, it was printed with a different book cover. I am saving it as a collectible item for when I make it big
Hope this is helpful information, Stacey
