To export several sets, go to the exporter. If you use the data I'd really appreciate a link back to Brick Insights. It keeps this site going.
Without a doubt, Set 2 is superior to Set 1 both in terms of the final model and the parts used in it. It stands to good reason that it is, because it was the more difficult set to get hold of. Although the promotion lasted for just three days, amazingly some people weren't able to get hold of them - probably losing out to the scalpers and resellers with deeper pockets.
