>>10870750For me, the first place goes to none other than 10244 Fairground Mixer:
It is nothing short of amazing how the entire set can be collapsed and folded onto a single large truck to model a mobile carnival ride truck. The main ride works incredibly well manually and can be easily motorized, and if that wasn't enough, there are also smaller games like a dunk tank, high strike, and a juggler on stilts. The set comes with 12 fucking minifigs, all unique to this set, and at $150 was priced 8.6 cents per piece.
Not so sure about 2nd and 3rd places. Really depends if you're factoring price into the rankings or not. LKC is great, but I think the Barracuda Bay was better value at half its price, for example.
