Zip and Piz are good and are supported by most industry software that support OpenEXR. It depends on your final resolution. For example at 16k, 8k, and 4K resolution the data that is lost isn’t noticeable.(So say the experts. I haven’t done the testing) When you start getting to 2k, 1k, UHD, and HD it becomes a little bit noticeable. The issue that I have with it is the additional overhead(More CPU usage) that is needed to decompress the DWAA and DWAB. So, basically it boils down to longer processing times in exchange for saved storage space. PNG in my opinion is a better option if you need to save storage space.
