I have no experience with PC-SWMM, so I can't offer a point of comparison, but if you need to tap the brain of someone who's done quite a bit of XP modeling sometime later in the project, shoot me an email. Their graphing module was bought from some third party, and is terrible, and buggy, and doesn't give you the basic sorts of options that anyone who's ever had a Technical Communication class demands. In order to get any sort of graph that was remotely worthy of including in a report we always had to export node or link data to a text file, import to Excel, and do our own graphs by hand.


The two major drawbacks I see with XP are the cost, which is exorbitant, and the data presentation, which is generally horrid.

Can't answer either, but I've been an XP-SWMM user for most of the last decade, and I can say that XP-SWMM stability issues have gone away, provided you're not working with a model that's been "upgraded" through three or four versions, or has been subject to a lot of data imports from nefarious sources.
