The answer is going to be more complicated than just which is best. We are about 5 months into AC and the EHR conversion, and have had to put a WHOLE lot of effort into the general office flow. There are lots of tasks that have to be accomplished in an office, different offices have different needs and priorities and consequently a lot of philosophies of how to accomplish these tasks. Each of these services looks at it differently.
We went with UpDox because we needed to quickly get set up for electronic faxing and a patient portal, plus a way to import items without having to learn yet another program like Adobe right away or train someone to do importing. I am fond of Updox, but have no standard for comparison. If you search for Updox during the last couple of months there are a bunch of threads. We are happily using it for incoming faxes and in place of a scanner (we just fax to ourselves) as well as the patient portal that we use a lot. Updox remains a work in progress, it is improved almost weekly, and tech support is outstanding. It was also fairly easy to learn and use which was vital, as we were really stressed by the whole conversion process.
We have not much used UpDox for outgoing faxes as there is an issue with the Updox phone service that does not let it fax to Alaska, so we use a fax modem on our printer. I think that is still the easiest method for outgoing faxes although it does mean a duplicate address book.
There was a recent thread on Paperport also that sounded to me as if the current version was giving problems, but as I said I have no experience with it.
