Ultimately, Sketch and Photoshop are without doubt the best design tools.
Sketch definitely paved the way for the new era of design tools, but has quickly fallen behind in features and implementation. I don't think Photoshop was ever a good design tool, and I will never understand why people continued to use it over Illustrator in the pre-Sketch but post-skeuomorphic design era. The only thing it did better was rasterizing gradients.
I'm not sure how much room there is for separate prototyping tools like this, Zeplin, or Invision when tools like Figma or Invision Studio have it built in. Especially if you want to prototype non-static screens with sections that scroll independently for example.
