I have used the POR 15 two times. It worked well the first time,thats why i used it again. Thats the only one ive ever used and my friend that referred it to me has used it numerous times.
Im happy with it and he's happy with it.
Im sure theres other prod's. out there that people have used and they have their reasons for liking them,but for me,its POR15.
Good Luck with whatever you use.
