Thoughts about latest UXPin release?

Hi All,
I’m looking for experiences and opinions on the latest version of UXPin. I think it has great potential and am about to start using it along with Sketch instead of Omnigraffle. Would love to hear from anyone who uses it on regular basis. What are your likes/dislikes? Is it easy to learn? What is it missing? How can it improve? Thanks for your help!

Thanks so much! The reason I asked about Sketch is because they now have an integration feature for both Sketch and Photoshop to make more realistic prototypes.
