Figma

Cloud-based, works on both macOS and Windows, very easy to collaborate and/or share design files across the team or to the client. Coming from Sketch, the UI is very similar and I was able to start designing with virtually no adjustment period. From what I understand, interactive components with independent animation states should be released soon in 2021 — that should make Figma a suitable replacement for the Sketch + Principle stack I use currently. Being able to share design documents, animated prototypes and specs within a single service would be a killer-feature.

Subjectively, on my 2012 Macbook Pro 15-inch with Retina the app may run slower than desired sometimes. Overall can't think of anything in particular that I wouldn't like.

The speed which Figma is operating is incredible and the possibility to have it working in any browser is great. The best feature at this point the the very advanced auto-layout function and the benefit of seeing fonts rendered actually in a browser - so there come no surprises later at development time.

Shortcuts and plugins are a bit of a pain. You can not remap shortcuts at this point and plugins can be installed and used, but there is no way of "hiding them" or "deactivating" when not used and the menu list gets way too long.

Figma is easy to learn, and available on any computer thanks to its web-based capability.

Versioning comes in very handy, as well as commenting, sharing, and fairly user-friendly prototyping features.

Figma is affordable, but scalable. You can have a very robust UX team utilizing it. It's a user-friendly wireframing and prototyping power house.

While it's easy to use, there's still a learning curve. I was a Sketch user, and Sketch is still faster to design in.

Also, if you want a really complex prototype, it can get tricky.

And, having a local version of Figma is still cloud-based. So, working offline will give you limited capability.
