Both are actually best as they will both do a great job.
I have hunted with both in my 30-06 and prefer the Accubond as they do result in less meat damage. With the 180gr. SGK (almost identical to the PH) I shot a Kudu, full frontal, from about 50yds, when we got to dress the animal the insides were one big mush, had blood all over me. Shot a Kudu behind the shoulder with 180gr Accubonds, there was a 0.5" exit wound, the liver was still in tact for eating. The 165 Accubonds are similar but the exit wound geberally is a little bigger as the bullet deploys a bit more.
I would also point out that for me the Sierra's still shoot more accurately but from a hunting perspective the amount is neglible out to 300yds. My hunting bullets it the Accubond though.
One word of caution. Most my bullets a boat tailed, not for any specific reason but it just has worked out that way. Out to 300yds it is widely believed that the flat base bullets like the SPH deliver superior accuracy and that the streamling effect from the boat tail ony comes into its own after that. Anyways I digress. Recently I was loading flat based bullets in my .375 and was getting very poor velocity spreads, my friend loaded some for me as a control and his "identical load" beat mine hands down. After a bit of thinking etc. I decided to take more care on seating, with the boat tail bullets they slip in real easy and I though perhaps the flat base required a little more care. I brought the ram up until the mouth of the case just touched the bullet, I then gently lightly tapped the bullet using the press handle believing that this would better centralise it, I then applied very gentle and even pressure and seated the bullet slowly. My average std deviation dropped from 24fps to a little under 4 fps.
My go to load for my 30-06 is a 180gr. Accubond at about 2 620fps.
Finally, I find the recoil with a 180gr bullets to be more acceptable than the 165's or even 150's. With the 180's you experience more a heavy push but with the slighter bullets more of a harsh jerk. Neither are bad the one is just more pleasant to shoot IMO.
