For me i'll choose burial.. Becoz burial is one of the oldest form of proper disposal of dead body.. I want burial.. Because in burial.. Like nuff said. Your remain still intact in the tomb where you buried.. At least there a proof that you'll exist in this world..
I kind of disagree with what you said there that your remains will remain intact dude, The proof you're looking for won't be found where you're buried but with how you lived your life. Your tomb would only be as good as the encryptions in stone. For me it's the same. Whether you're buried or cremated, your existence and remembrance will be judged by how you lived your life.
