Why are you surprised? Some companies do have products of high quality, the others are trying to copy them for the sake of profit. At first glance it can really seem we're spoiled by choice but in fact there are only several decent raw converters and dozens of low quality stuff for making money. I use the one mentioned by @Photogezeer - https://macphun.com/luminar/raw-converter. Reasons? 1. I'm not a professional photographer, and it's easy for me to use.2. HSL filter. 3. White balance. 4. Possible to export to Photoshop or jpeg.
