I have reached the point where I insist on installing a SquareD PK4GTA ground bar in a 3 gang switch box and a 7-terminal bar in 4 gang and larger boxes. For the number of ground wires this is the most reasonable method. For plastic boxes I need to refit the ground bar with longer 8-32 machine screws.
I have also come to like using Ideal's Insure wire connectors for some applications such as equipment grounds and neutrals for 2 reasons:
1. The silicon carbide paper elbow grease electrical grease method is a lot easier than with Scotchloks.
2. Dr. Jesse Aronstein did some test for the Consumer Product Safety Commission which showed that putting 5 or more 14 gauge or larger copper wires into a Wirenut or Scotchlok is asking for trouble. My experience with say 27 year old 20 amp copper wiring bears this out.
