They are more stable at higher RPM, it is a factor of safety for me. I won't be spinning more than 7000 RPM, the LS7 OEM lifters would have worked just fine.
We haven't had any issues out of the 100's of sets we have used here. The ceramic check ball can be noisy depending on preload and the valvetrain that is used with them. In general, they will be noisier than the LS7 lifter though.
Most bad reviews tend to come from lack of valvetrain control, improper preload, or using a spring that is way too stiff for the lifter.
