Sketch vs Figma

vs Adobe XD

Light , quick and lovely interface
Live prototyping, wireframing, auto grids
Amazing new possibilities regarding workflow, and combined with adobe creative suite (XD & Photoshop) you can realize some really wonderful projects
Available on both Windows and Mac.

Sketch: Not natively, but a plugin Picnic is in progress
Adobe XD: Live collaborating will soon be available through your Adobe ID.
Figma: Yes! Not to mention being browser-based allows Windows and even Linux users to have a very polished design tool.

Sketch: Not natively, but because of Sketch’s rich community of plugins, plugins like Craft allow mobile prototyping from within Sketch. Also, most third party prototyping tools play well with Sketch files.
Adobe XD: Yes, native prototyping within the app.
Figma: Yes! It's very basic, feels like Adobe XD without the transitions. Also, there's a nice Framer integration).

Sketch: Mac only
Adobe XD: Mac and Windows but, features are prioritized out for the Mac version
Figma: Other than browser-based, apps for Mac and Windows but not offline capable
In an AMA they stated they don't have any current plans to add it either

Sketch: Not natively, but apps like Zeplin and Avocode were made specifically to deliver Sketch specs to developers. There’s even an entirely free alternative called Sketch measure that works just as well.
Adobe XD: Coming soon.
Figma: Because of live collaboration, developers can easily jump in (regardless of OS) and access the designs.
Every Figma file has Code Mode where developers can inspect design files.
It also neatly prints the handoff code for CSS, iOS, or Android in the right panel.

Sketch – No built in ability for commenting, will have to rely on Invision’s commenting features or Craft’s “freehand” plugin.
Comments in each solution are stored somewhere different than Sketch.
Figma – Commenting is built in and just as nice as design collaborating.
Adobe XD – Has a commenting feature, but it’s not really built-in and can only be done once you share your project online through Adobe Creative Cloud services.
