I would heed the Nosler recommendations. I've used the 30. cal. 150 TSX and TTSX and the 150 E-Tip. Same powder charges give about the same velocities for all the bullets. I use mostly H4895 in the .308, and occasionally Varget. As for the 150 GMX, I got about 50 fps more velocity with the same powder charges used for the E-Tip and the Barnes.
Seems I've also used the 165s in all persuasions, but my notes don't show anything on the 165 E-Tip. Barnes and GMX, however, show about the same velocities with the same powder charges.
In the .308, I've used only the Barnes 168 TSX BT on game; several bull elk and the bullets worked fine.
I've found all the bullets you mentioned to be reasonably accurate in .30 cal. However, for what it's worth and based solely on my limited experience, a good load usually comes sooner with a Barnes TSX BT (not the tipped bullet) than with the others.
