I would say that WideOrbit is much better than Pilat in terms of its ease of use. One major factor was that WideOrbits customer support is stateside and easily reachable if help is needed. Pilat was located in Europe I believe and getting assistance was very hard. As far as just the overall day to day usage, WideOrbit is leaps and bounds better in the area of functionality
Rubicon Project has made it easier to optimize so that we could get the fullest ROI on our inventory through their alerts on which deal needs troubleshooting.
They also send a daily report which notifies you which advertisers have low render rate which is very helpful when figuring which creatives need to troubleshooting.
The system doesn't seem to work well with any of our digital platforms. For example, we can input an order and track an approval process through our finance system and see the invoice, but actual execution of any digital assets are NOT done through Wide Orbit
