I´m always a bigger fan of pmv´s; the issue is that as g90ak already mentioned it´s a lot more work and the music is always hit and miss for different people. While specific music can make something way better, the wrong choice can make it unwatchable.
In the end it´s your decision, right? It´s just that there´s an overall lack of well done cumshotvideos, especially in a pmv-format
Btw, thanks for all the work you do here 
Just in general
