Pound for pound equal,but not the same

I had some pcgs and ngc coins.I checked out both and about 12 years ago I decided to stay with ngc.Pcgs commands a preminum,but they do not have as many dealers sending coins to them.I had pcgs coins that would not cross to ngc.Ngc does 10 times the volume than pcgs.That should tell you who is more trusted.Ngc accepts pcgs becaues the consider each other equals.Pcgs on the other hand wont,and my guess is that because of the volume ngc puts out,the pcgs registery will be the second ngc registery.Pcgs is losing in the certification market place.They eventually be a memory in years to come!!!!!
