SAM just means slower and quieter AF.  Screw-drive is faster, and for  fast action telephoto lenses, it's what you need for quick subject acquisition, panning, framing, focus and shooting.  Don't get hung-up over HSM/USD/SSM . . they just mean slower and quieter.  You can't beat screw-drive for the reasons stated (it's what I use mainly) and after buying both SAL 70-300 and 70-400mm G SSM's, they went straight back as they were simply not designed for fast action (I'm sure they're fine for slow moving or static subjects), so consider your need when choosing lenses as just because the latest model has a new feature, it doesn't mean it's better. So to summerise, SSM/USD/HSM for slower, quieter situations and screw-drive for fast action and rapid focusing (especially with CAF selected) like motorsports and aviation.
