The old image picker was so much better that there's no legitimate comparison, because the old one allowed you to use your gallery app, which is my case is Simple Gallery Pro from F-Droid because it's the best one there is. I just went from being able to search my microSD card by filename to having some kind of web 3.0 abomination that just shows every picture on local storage in a feed, and an album pane with a whopping 3 albums from local storage. Massive, massive step back. Potentially a deal breaker.
