For me, what you're describing here is an issue with the designer, not the software capabilities. I can frame a website in no time in Sketch without ever getting to the style and aesthetics.

Hell, I can even make a presentation of an idea, how it'll work and not even touch on the buttons.

I didn't understand why I should not be using Sketch at all. Try positive title next time and, just a suggestion, talk why you're better, not why other software is bad...
