I like 5" barrels, I have a model 29 classic hunter that is just stellar with 300 grain bullets, and mediocre with anything else, but because it has a scope does not count,, my 4" gun is an old model 57, .41 magnum, and with any lead bullet is a tack driver, jacketed bullets are ok but not killer, I have ordered but not shot yet, some 270 grain bullets with a big meplat, that I think will be the hoss, but as with my .44 mag, the rear sight may not have enough downward adjustment, unless I replace the front sight.
