HOM by far if it’s built relatedness-- coming in against a ‘challenger’ True Sell might be as good.
HOM hits or doesn’t with creating connectedness, and if it does not True Sell outperforms agains difficult people/and situations and ‘pitching up’.
Khan and/or ASBR stacked with either AOW or True Social would outperform HOM in power talks and negotations currently thought I believe.
On my stack, which includes HOM and True Sell, I find myself allocating space for winning somewhere else rather than dealing with difficult negotions. When I stack with Essence: Total War and Khan, I dig in to win everything I choose/want.
If you 'selling up/pitching- and not necessarily on an equal playing field, True Sell might take the edge, but HOM can create relatedness that creates parity.
