I always have difficulty in deciding which of my American pumpers (Benjiman 312 and 347, Sheridan Blue Streak and a Crosman 147) I like best.
I'm only a plinker so power is not all that important as they all make tin cans bounce!
Really, for me, much of it boils down to looks and to be honest I think the Crosman 147 is the most elegant although it is not my first choice for a plinking session -- that has to be the tootsie roll 312, 60 years old and still going strong, easy to pump and decent sights.
