It looks really good on the paper. Marketing departments are always doing a great job of making something look great on website presentation or paper. I was actually very excited about it... when i read they support everything from MentalRay (which i know) and that they have overcome most of the limitations. And that their interactive rendering is really seamless. But once i tried it, actual truth was very different.
Lots of things are still not supported, or working in a weird manner, and the main limitation - GPU memory- which Redshift has found some way around, is present in moskito... so unless you have at least Titan Z with 12GB RAM, there's not much of a chance to render some more complex scenes.
Usually, you see some well built web presentation and hype video, and then once you try yourself, you are disappointed. I like Corona because Ondra does the exact opposite. There's not much of an aggressive marketing trying to oversell the product, and once you give it a try, you are pleasantly surprised, because it is above your expectations, instead of below them.
