StormCAD vs. Inroads Storm & Sanitary software

[TransCivil]

Looking for someone who's used both to give me their opinion?

Needing drainage software and I'm not sure which one will be better for calculations. I'm just getting into drainage design, but I'm an advanced Inroads user, so Inroads sounds good because I can use the DTMs and alignments directly and also do the drafting right in MicroStation from Inroads. I don't want to skimp on the calculations by going to Inroads Storm & Sanitary.
Thank you in advance.

You could start with Inroads and confirm the calculations by hand. It may be cheaper to "Add-In" the storm drain piece rather than purchase Stormcad. Just make sure, before purchase, it will meet your local gov. entity's requirements.
