A workhorse of seismic processing software
What do you like best?
I like Kingdom because it can get the job done. It may not have all the fancy bells and whistles of other programs, but it can do pretty much whatever basic thing you need done, plus it's generally much more simple to use.
What do you dislike?
If you have something really specific and specialized that needs completion, chances are Kingdom can't do it and you will need to turn elsewhere. Integration of other data is also tricky.
Recommendations to others considering the product:
Use it for quick and dirty data output. Save the fancy images for other programs
What problems are you solving with the product? What benefits have you realized?
Kingdom is great for providing a fast initial product with new data. It helps us get a feel for the dataset and figure out what else we need to do with it
