I've wrote a review to Lumion V8 but it does not appear. Now another try:
I often hear that the program itself and the updates of Lumion are expensive.
I use Lumion since V5 and every year they give us a big update.
I was a former user of Fryrender and Thearender as hobbyist/semiprofessional.
Now the quality of the V8 hasn't reached all of the possibilities for example of Thea, but overall I have so much more possibilites with an incredible speed.
The library of objects like plants, cars, people, materials, lights grows each update.
The realtime-tweaking of the sun, weather, effects helps me building my scene in very short time. I can work on the landscape, have mass-placement of animatable plants, cars and people, a video-editor, sounds which are placed at certain places and so on.
Lumion is so much more than a renderengine and since V8 nearly comparable in terms of quality to other renderengines, especially for architects.
Now Lumion 8 can illuminate a scene with indirect skylight and that makes the big difference to V7.
See my attached picture. Rendered in 50 seconds on my notebook with GTX 980 for Full HD.
Here an animation, rendered about 7 hours on my notebook. Please excuse the crappy camera-path.
Only lit by the sun.

Here an animation (a bit kitsch...) for a client:
