I`ve used both to form two of my companies.
they both provided a good end product, which is an incorporation service. But the problem that I had with legalzoom, is that they are not attorneys. i had a bunch of questions for them and they could not provide legal advice?? that`s because they are not attorney`s but a document generating service. I fealt kind of misled since they have a photo of shapiro on there.
complete opposite with amerilawyer site. they are real attorneys and they will answer all your questions. I fealt really empowered after speaking with them. I recommend them completely, plus they provide a more affordable service.

I`ve used legalzoom and bizfilings. I prefer bizfilings.
Legalzoom does the job but they have so many "partnerships" fielding the sales calls becomes a burden.
If you have the time just go to Ca. Sec of State portal, performa name search, print out the forms, file them yourself. Much cheaper. You can get the by-laws at a big box office supply store.
I haven`t use bizfilings yet.
the thing that i liked about amerilawyer.com is that they customized everything for you. the articles and by laws were very thorough. plus you get to ask all the questions you want from one of their attorneys. i was impressed with the service. the funny thing is that you could never ask bizfilings are "shapiro" any legl questions. they won`t answer them because they`re not a law firm. and that`s why i was impressed with amerilawyer. I really fealt confident after finishing my consultation with the attorney. (thanks Mr. Hardy)

LegalZoom is a really great company to work with. Their support and advise is really prompt and good.
I used Perfectdocs, because I found a good discount code for it "attorney1" - think it is 50% off. I had a good experience. These forms could give you some information and guidance.

good luck
I have been using Amerilawyer for a lot of years and I am very pleased with my choice, others are using Legalzoom and after a couple of months they realized All Pro is the best and they start using Amerilawyer. If you can find a discount code on Perfectdocs you should definitely pick that.
