Default Lucas or seafoam?

I have read seafoam and Lucus is the best for fuel system clean, but then I have seen Chevron and Amsoil is the best. I only have 62K and no problems. Should I even bother with this? Do I risk screwing up plastic parts in my engine? I heard these additives can cause wear on plastic parts? I know seafoam is best for cleaning throttle body and intake. Has anyone had any problems?
