Your made really great points, but it looked like you were searching for just one or two softwares that would be able to handle all your demands and not assuming the possibility that all of them would complement themselves.
Sketch and Photoshop can coexist in your life the same way they live peacefully with Illustrator, InDesign, AutoCAD, Lightroom and a few others for 3D editing, sound editing, video editing etc. Even though their features overlap (the same way illustrator, indesign and photoshop overlap some features) they have different strongholds and do not compete directly necessarily.
Anyway, what I mean is: "Good thing you didn't cancel your Adobe subscription, that thing is still bloody useful".
Nice blogpost anyway, cheers ;)
