If by 'springer' you mean any type of gun that uses a single cocking motion to load and fire the BB, then it's usually not good. However, if you have something that normally shoots one projectile/burst of projectiles at a time anyways, like a Sniper Rifle, or a Shotgun, then that's as far as you get. There are some very, very good spring sniper rifles out there, although with shotguns, I prefer gas.
But, like MaciekA said, the term 'springer' is usually only reserved for the cheap clearsoft (if it can even be considered that) that you normally find at, say, Walmart or the likes. It all depends on the gun.
