I can not say enough about this kind of support. Very rare these days. I have no problem telling you that your purchase will be supported and will work.
Although this is not the place for an in depth review of all three, I will say that no matter which one you choose, unless you are just using it with its default settings, be prepared to spend some time creating support tickets to get your answers instead of saving days of time being able to read in depth documentation.
Waiting for an answer on how to resolve this from the developer.
