I had them laminated prior to playing any games so I can't comment accurately on comparing one versus the other.But in more than a few games, one significant table bump and another incident where I swooped over the cubes on my mat with the rule book only resulted in having to re-organize them a bit. Nothing made it to the floor and I don't think any even made it off the mat.
The only downside is the difference in finish on one side versus the other - one side is shiny vs. not shiny. I'm pretty anal and have come to terms with it. If you're like me, than I would recommend doing all the humans and magellan so that their side is the same and the single races as the other. Doing that helped in some way for my mental well-being.
