Cam grinder/manufacturer opinions

For most mild builds or moderate street cars is mainly what I help people with, I’ve been using Lunati for years.
Cams seem to have a little more duration at .050 while keeping the overall duration down. Lift numbers seem a little higher.
So I assume they have a more aggressive opening rate. Works on Mopar and Chevys
Custom stuff I’ve used Bullit and Lunati, comp cams years ago had some problems with them.
