Unimus vs Solarwinds NCM for cofinguration management

The organization I work for is evaluating network configuration management tools with the intent of spending money on one. The contenders have been narrowed down to Unimus and Solarwinds NCM. I have past experience with Solarwinds NCM, so feel like I have a good handle on what to expect from it. Recently, I've also had the opportunity to evaluate Unimus and it seems like a pretty good option. Do any of you out there have real world experience using either in your network that you are willing to share about? What was great? What gotchas did you run in to that maybe were not obvious until you had been using the software for a while? I guess I'm particularly curious about Unimus since I've used Solarwinds NCM in production in the past.

For reference, our network has about 1200 nodes (and growing) that we back up, push changes to, etc.

Thanks!
