Your opinion is shared by quite a few gun experts. I guess it depends on how much you are trying to "push" the envelope of a given caliber. I would use premium bullets in 6MM-284 on mule deer, and premium bullets in a .270 on elk. Very often, the "premium" bullets give more penetration at the expense of a smaller wound channel - which can result in less-than-quick kills on broadside rib shots.

Of all the new high tech bullets, the one that has really impressed me from a terminal ballistics standpoint is the Swift Scirocco. Not really much more penetration than a regular bullet, but a very large wound channel that happens right in the middle of the vitals - putting the animal on the ground in a hurry.
