How thick is your hair? If it's really thick, you may like the Ouidad cut. It will really thin your hair out, and it will take a long time to grow out.
IME, with a varied curl pattern, extremely fine hair which isn't thick, and 3B curls, it was not a good option. Also, cutting it wet meant that the stylist couldn't see what each carve and slice did to my hair.
OTOH Deva cuts work brilliantly for my hair. Cutting it curl by curl and dry, the stylist could see how each snip interacted with the rest of my hair, and there are no nasty surprises at the end.
