Help with Affinity Photo.

Hi all! Adobe decided to take away the version of photoshop I was using from the creative cloud sooo I am screwed for now. Until I can get a new PC at my location. Anyway I do have Affinity Photo and I was wondering if any of you know of good, quick, and easy tutorials to help me get over the learning curve?

Also how do you feel about the output of Affinity vs PS?

Thanks.
