Coming from someone with experience, I'd rather have frame sliders than none. The extra couple inches of elevation help protect your leg in an event. The plastic really does not grab at all, so the only time where your bike may flip is if your wheel catches a curb or something. Lots of times the frame "slider" itself just breaks (it's plastic after all) and the only thing left protecting you & your bike is the elongated bolt.
Depending on your bike, a cage may be overkill. I've got sliders on the engine-frame bolts, solid bar-ends, and a wear pad on the outside of the passenger foot rests. Aside from wearing down the footpegs, my bike was demonstrably protected in a slide even with a broken & bent slider.
All aside, if you've ever taken a real spill you'll know that protecting the bike fairings is the last thing to be worrying about afterward. I'm sure you already have full leathers and full length boots right?
This. I`ve seen some pretty nasty spills, and with sliders alone the bike was still in decent shape.
Just good sliders (and for the back of the bike too if they make any) along with good bar ends and that should do a very good job at protecting it. Unless the bike slides into a curb or a car (etc etc), then there wont be too much damage.
