You just don't find people bitching about or even questioning the effectiveness of Partitions. I should say that it's rare. There are hundreds of threads across the internet questioning the effectiveness of monometal bullets. In each of those threads credible posters share experiences of some level of dissatisfaction. In those same threads, very credible posters heap praise upon them. My comments are not meant to take anything away from them. Anything that could be said for the Partition could be said for the A-Frame. I have read a lot on the A-Frame, and I think the front half is a bit tougher. My experience with the Partition on deer size game is 100% positive.

In Order

150 Partition
150 A-Frame
130 TTSX
150 TSX

I know you didn't ask about these, but they possess characteristics of monos, bonded and Partitions. I have some on order and have confidence in them. I'd put them on your list above the Barnes bullets.
