I have to throw out there that no matter what you choose, the real winner here is the sound editing/audio engineering. As a kid, there were certain qualities about the movie that stuck with me for years and as an adult I recognized it as excellent audio engineering.

From the crackling/sizzling of Harry's just-extinguished burning scalp to the sound that nail makes as it drives straight into the arch of Marv's foot, you hear everything perfectly. Watch it again with your eyes closed and the sounds are so visceral - even when they're dangling from that rope, you hear the creaking from the tension and then as Kevin uses the shears, you hear every fiber of the rope snap. Add to that the fantastic performances by Pesci and Stern, they have to make so many grunts and shouts that it should start to repeat but every one is different and believable, if a bit cartoon-y but it works!

That's good film making. As for me, the glass ornaments were always top-tier, the sound they make as they explode under Marv's feet and his squeals. And then after that when you hear Marv stepping on the hardwood floor you hear the little "tinks" of the glass embedded in his feet - just vicious. Its that very over-the-top quality that sells the comedy, for me.
