Sure! All those are excellent tools, so let me go through how Mitya differs instead :)

I believe getting from blank screen to animated prototype is just a lot faster in Mitya. You can watch this video to get a feel for how quick it is to prototype: https://www.youtube.com/watch?v=FyDq04Kbolg. You have very few steps - which allows for more experimentation, IMO. If you recreate that demo in other tools, you'll see the difference :)

For me, the advantage of this flow is that your screens and states are always visually laid out in front of you. This makes it a lot easier to 'play around' with ideas. And when you return to a prototype you haven't touched in some time, it will still make sense. Playing around with code is a little more involved - possible, but more involved.

Also, the timeline editor makes it very easy to tweak your animation's timing without having to mess with numbers. This way, you can animate based on how something 'feels'. When you work with numbers, it can sometimes be tempting to round them off, for e.g. to 0.5, just because the number looks 'cleaner'. But when you work visually, you can leave it as 0.492 if that's what feels right.

That's my take on it. And, of course, there's a free trial on the site. So, please do try it out :D
