They're both indy, so's this one, the other two have quite a professional quality to them - given they're very well put together and are capable of high quality material. I'm assuming this too.
For 'professional' you're looking at an aweful lot of money.
However, demos aren't everything, the Unity3D demo isn't as nice (the Abyssal Engine Tech Demo 'looks' nicer, but all you're really doing is exploring a scene), but the tutorials you start off with help you get you through to getting a good quality demo made. Leadwerks has a good set of tutorials to show you how to get started and help you understand how everything works so you get the most of the features. If you can get kicked off into making something higher in quality, then I see more purpose in a trial than something as superficial as demo.
Saying that, I've not yet downloaded the trial for this, nor am I shooting it down (it looks quite good and well, TGC give their thumbs up.
), but it sounds as though it's the tech demo that's impressed you over the two alternatives you've highlighted.
