This is a hard question to answer. Almost everyone will have a preference for a particular cut based on several factors. I can purr well on most diaphragm calls but getting a solid yelp out of them is difficult. As far as yelps, clucks and cutts are concerned, I tend to gravitate towards either a V cut or a sawtooth cut. Have a gooserbat hillbilly that is a modified v cut. It's a good one. Aside from that, it he HS strut ma' deuce and split v iii have been my go to calls for a while.
