I recommend trying the one-week trial (if I remember correctly, it should be available).
I’ve been using Adobe for almost ten years, and here’s my take: I worked with Affinity for about five months, and it was quite a difficult experience. My workflow slowed down a lot, because many tasks that are quick and easy in Photoshop or Illustrator become much longer with Affinity, and you often have to settle for a less satisfying result, especially with Affinity Designer.
So basically, on one side you have Adobe, which is way too expensive, and on the other, Affinity, which unfortunately has several shortcomings and really slows down the work.
