I’ve used SketchUp ever since version 5 with @Last Software. I ran a model through the full version and got some pretty cool results – after playing with it for over an hour I came up with a lot of different renderings that, while they are still computer generated, give the rendering a much more fluid look.
I’ve been designing this building straight from a BIM model but gave up on the aesthetics and went to Sketchup. These days, more often than not, I design purely on the computer, for better or worse. Regardless, the abilities of the full version of this software make me happy.
