This is just my personal preference, but I like version 2 the best. The flowers don't hurt my eyes like the first one, and the text underneath are smooth and more readable than version 3.
I agree about the text, that the second one really looks the best, because it's readable, this is really a nice signature, but I don't know if it's me or the signature, but I would prefer to use it only if I would be a female, maybe because of the flowers
