I wouldn't let the horn status of a bull decide whether or not I use a bull if I like the bull, but I would rather have great polled genetics. I don't like it @ all when I buy a "POLLED" bull, then get scurs or horns. That upsets me. I like to use dehorning paste, but like Elbee says with his method, it has to be done right. I like to do it day 1 while the buttons are soft. If done correctly, I would challenge anyone to tell if the calf ever had horns.
