I'm late in the game (having been in the Caymans all last week), but I find JP2 more difficult than GeoTIFF simply because the open source tools for working with JP2 through GDAL seem to be significantly flawed. The Kakadau (I think?) JP2 library seems to resolve a lot of this, but the end result is not an Open Source tool, so far as I'm aware: this matters more in terms of my personal (non-commercial) projects like OpenAerialMap, where I can't take a GeoTIFF, reencode it to JP2, and use that as my base imagery for 'free', either libre or gratis. I have had some success with JPG-compressed GeoTIFFs, but these are lossy, and that causes problems (obviously): uncompressed GeoTIFFs are also problematic due to their raw size. (This answer to the question may be irrelevant, as I'm jumping in in the middle of the thread. If so, I apologize.)
