I am a long time user of Photoshop. I have CS6 of it. But I have no intention of going into the cloud with Adobe. So this leaves me with a dilemma. I will be using PS for a while yet. But eventually I want to migrate over to another alternative App. I am not a pro user. Only casual. But I do use some of PS's nice features. I see 3 main alternatives. Acorn, Aperture or Pixelmator. $31, $85, $16 are the prices for me in the App Store. The question is which one would be the best for me. I have no qualms paying $85 for a good piece of software. I've only limited experience with Pixelmator of those 3 and no experience with the other 2. So which of these 3 is the best option in your opinion? Which one should I go with?
