Should I use JavaCV or OpenCV's java wrapper?

I am going to write a CV program in Java/Swing. I can't decide between JavaCV and OpenCV's official java wrapper. Main

Altough OpenCV's Java documentation sometimes lacks, it seems that JavaCV has no documentation at all (except for a few old examples)
JavaCV has some own classes, for example CanvasFrame (seems to simplify GUI creation)
As OpenCV does not have a complete HighGui module, it seems that I would have to copy entire Mat object to BufferedImage point by point when I want to display it. Does JavaCV do this in the background? Or is the image showing faster when done with JavaCV?

I have worked with both api from opencv to java and javaCV and I do recommend you to work with the api. Mainly because of the documentation. Also if you dont find examples exactly for the api use, you can easily read either the c++ or the python implementation and try to find out how in java. I have realised java implementation and python are very similar.

About the gui, you can use gui builder for java. And to display an image you can create a function where the input is the image to display. See http://answers.opencv.org/question/8119/how-to-display-image-on-java-release/?answer=32135#post-id-32135
