"Best" depends on what you're after and use. All my working guns( Savage-Stevens) have Timneys, the paper punchers-vermin guns SSS Comps. The only reason for the Timneys over RBs, I made a guy at a show an offer he couldn't refuse, take the ten home or what I offered him for the lot. He liked my money more than the triggers!
The other three have ATs, they're my three grandson's 14s. I haven't used the RB SAV-2s.
