So far the three mentioned products - XMod, Dynamic forms and Enterprise forms - all seem to address the same or at least similar purpose: form buidling, data-access, workflows etc. Is there any more detailled comparison available/possible? Does someone of you already tried out the products and can compare them?

I use XMOD quite a bit.  If you want to create forms and don't want to bloat your DB with one-table-per-form then XMOD is great.  I have had occasion to create hundreds of forms over the lifetime of some DNN instances so this is a big deal for me -- after all, who wants hundreds of old tables of surveydata mixed in with your "live" DNN tables?

If, however, you DO want to tie a custom form with its own DB table then XMOD is not the best choice (although the new XMOD PRO module can do this).  also XMOD does not make it easy to execute stored procedures (unless you create an ASCX-based form) or otherwise manipulate data in other DNN tables (though, again, XMOD PRO now allows this).

I think Dynamic forms probably has the easiest form builder tool (WYSIWIG drag-and-drop).

XMOD is better for hand coding (similar to a simple HTML page) or using Visual Studio to take full control and create a custom form (plus any of your own .net logic) via ASCX web control.

Personally I think Enterprise forms is one of the most underrated modules due to the misperception that it is too complex and hard to use.  I guess that is the price of being flexible and powerful.  I have an early adopter of both Xmod & Enterprise forms, is by far the module of choice for developing workflow system.  By workflow I don’t mean the basic submit, approve, and reject type of workflow where the approval process is pretty much fixed.  With Enterprise forms you could create a workflow that can pretty much map to a required business process.  On the other hand I have to admit Xmod does have the edge over Enterprise forms in developing master-details type applications.  That said I still think features such as performing add/update to external databases (mysql, oracle, access etc), powerful conditional evaluation on form objects and workflow, advanced email engine and workflow processing plug-ins are worth looking at when reviewing a forms package.

Back to the original question, I think you really need to know what you want before asking the exact questions at the respective vendors’ site.  Putting general questions here won’t get you too far as everyone has their own favorite forms package and you’ll certainly get biased responses (like mine here :)).  However I do want to see a feature comparison grid of these forms packages with input from the respective expert users.
