Personally, I use to use Photoshop and GIMP but I have gotten to love Affinity so I bought the whole suite. Unlike Photoshop, you buy the program $40 I believe and it's your's plus all upgrades. Can't beat that.
I am not a graphic or design artist. I am "forced" to use Canva which makes things so much easier than Photoshop. It seems people who do have great design or creative skills gravitate towards Photoshop which does "everything". For a guy like me, I need something more simpler. I like Canva. However, I more recently found out about PicMonkey and Picart which seem to give Canva a run for the money.
