I prefer seeing the money shot.
Personally, I find it to be a nice ending to a hot scene. And it conveys to the viewer, especially if it's one of those 'powerful' ones, that the participants greatly enjoyed themselves for our viewing pleasure. Sometimes, they can be disappointing though. But for the ones that are abundant, I have to say I enjoy those quite a bit.
For instance, Rocco Siffredi's cumshot in Jenna Loves Rocco with Jenna Jameson is pretty awesome. Not only did the two of them look completely lost in lust with each other during the scene, but Rocco pulls out only to shoot to hard it literally clears past Jenna's face and over her head! Fortunately for us, the rest landed quite nicely all over Jenna's face. And that was rewarding. Also, any scene with Peter North blasting all over Christy Canyon is also a bonus. Especially in their scenes in such films as, I Dream of Christy, and The Coming of Christy.
