Anyone use Omniplan?

I am a HUGE Omnifocus user, and I'm thinking about getting Omniplan for iPad. I'm wondering if there are certain workflows that are better/worse for Omniplan as compared with Omnifocus. Is Omnifocus enough? I have OF for Mac and ios. I'd only get Omniplan on iPad.

 

Thanks, but this seems to be a thread comparing the MAC app to the iPad app of Omnifocus. I want a comparison of Omnifocus and Omniplan. Thanks, though!
