Darkroom / Photomator / or Nitro?
I am looking for a photo editing app that handles jpegs and especially RAW files that are not apple raw. I've tested each of the apps mentioned in the title but I want to see any longer term user opinions and experiences. I enjoy each of these tools however they all vary in their benefits and drawbacks in the short term I've used them (trials).
Ranking from a functional/feature POV:
Nitro -> Photomator -> Darkroom+
Ranking from simplicity and user experience:
Darkroom+ -> Photomator -> Nitro
Nitro is the latest one I've tried and it definitely has the most feature rich setup without becoming something like luminar neo. Darkroom is just clean, simple and creative. Photomator is great in performance, speed and UI but frankly the ML features are very outdated and I'm uncertain about it's future since creative studio. Apple photos app is also powerful but it's not something i enjoy using.
Prior to these testings I was a lightroom user, but alas Adobe shall be no more. I'm interested in functional sliders, features such a removal tools and batch editing/processing/exporting is a bonus. I think the one thing I disliked about darkroom was that I faced a few memory leaks and a few crashes and overall laggy while looking through 1000-3000 photos (not editing, just flagging and scrolling). Otherwise it's a solid simplified app.
As mention I'm asking for user experiences, if you have used or currently use one of these apps then could you share your experiences with bugs, development, and use case. The issue I have is finding any reviews and use cases on darkroom and especially nitro.
Other apps I've tried are luminar neo, on1, and thought of capture one or dxo but those are the upper premium options competing with lightroom, pricy but rich. Unsure if I really need that level of power. I also thought of rawtherapee and other free open source options but haven't tried them.
