The tervigon is a one trick pony unless you roll a decent psychic power on it. It's also kinda points heavy for what it does.
You won't go far wrong with the trygon or the toxicrene. Contrary to what you've heard, maleceptors do not suck. They are effective focused witchfire snipers and not half bad in combat with most grunt squads. If nothing else, they are a target your opponent will regret ignoring if he does, and a diversion target to protect other blunter monsters like the trygon.
The carnifex is difficult to justify, and I feel the same about the haruspex. Both of these fill roles that your other monsters fill better or for cheaper. I was surprised notto seen an exocrine on the list given it's just about your only long ranged ap2 firepower.
I've also found that monsters work better with redundancies. The easiest way to do this is to have two of each, or two of something similar enough to fill whatever role you have. For example I run two maleceptors, two flyrants and two exocrines, but I can alter this to take out the maleceptors for trygons or occasionally swap one for Old One Eye.
