I had hoped to check the three developers that I currently have on my system (Zoner, Polarr, PD8) - but life has intervened and delayed me. While it's still a fun idea, I'm running out of time on my Zoner time trial. They use a slow but steady subscription of $49/year right now, so it will keep moving up incrementally like Adobe products. This makes me think of iTunes and its occasionally nice interface that gets ripped to shreds at random intervals - my wife and I currently have very little clue as to getting music to Pods or Phones any more. Not my favorite way to play.
Still, I have a week or two. I'll try to grab a needs-work image and process with Zoner first, then try out the other two. I've already removed Elements X from my system so it won't be part of the game.
