Chain catchers are simply for those who do not trust their mechanics enough to adjust their front derailleur correctly. I would say save your money and find a better tech if your dropping your chain. The front derailleur is the chain catcher and adding an aftermarket piece is not going to the root of the problem.
there are plenty of instances where the quality of the mechanic is not at fault. sometimes it's environmental factors, a swerve, a shift in the rear simultaneous w the front shift, a bump, an anomaly. sometimes it's a combination of parts-fsa crank, kmc chain, shimano everything else, chainstays 1cm shorter than specified by shimano. sometimes the frame places the derailleur farther forward or behind the crank than optimal. sometimes the front derailleur was designed in chicago. manufacturer tolerances stack up.
i like the new red chain catcher. you can get it separately, without getting the front derailleur, and put it on any braze fd.
with frames dropping in weight and pros having to fill up with lead to be legal, more and more frame companies will be integrating them into the frames, like the trek damone. at the same time, having the chainrings spaced further apart a-la current shimano has helped a lot...
