Goose, not nwhat you wanted here but all I have shot is paper with both bullets, which may change come this fall though. I have read lots of posts on Accubond and a few on the interbond, it appears the accubond wins in penitration but the bonded portion remains similar. It also appears the Interbond retains a bit more weight & mushrooms more so than the Accubond, which may account for less penitration. However like anything else I think certain individuals favor certain ammo manufacturer's so comparisons can be a bit bias in the field. In my paper shooting a slight edge in accuracy goes to the Nosler Accubond and I will most likely go with the 160 Accubond vs 154 IB in my 7 rem mag this fall if I choose to take the "New Bonded" route vs. Nosler partition or Failsafe this fall while chasing Elk/Moose.
On a side note I have had excellent results from both Hornady and Nolser offerings in the past, therefore whatever shoots the best out of my rifle will get the nod.
You may want to look into the Barnes Triple Shock as well, from what I have researched it seems like an excellent choice as well and appears the finckyness of the x bullet is gone with this new offering. Federal Premium is loading the Barnes bullet this year.

A number of reviews, tests and post on all 3 of these bullets over the past year.
PS what are you hunting?
