Just purchased. First thing I did was to try opening 6MB EPS file I tried to open yesterday (I've got Sketch & Pixelmator). Pixelmator doesn't do EPS. It took Sketch 1+ minutes to open one and it was practically impossible to edit (toooo slow). I dragged and dropped the file on Affinity, took less than a second to open and its a breeze to edit. I don't say it's a replacement to Sketch, but I say that it might be another great tool to complete your toolset.
