First thing comes to mind:
A Deathwatch Terminator (a 2W, T4, 2+, 5++ model): Cyclone missile launcher, Storm bolter, Meltgaun and Power fist is 114pts. Is 'only' 3 power if use in a veteran squad, if playing power. Granted power level is rare to use and even then
DW come out on the wrong side. But I have a few made and when playing Power level have performed well (among other wacky/expensive points combo's) and is always fun to use (Tele strat)
For normal, points games:
For Tau:
I know a lot on this site and others hate them but I have found XV8 Crisis Battlesuits with 2 Cyclic iron blasters and 1 Advanced targeting with some shield drones in support have worked well for me on many occasions (are expensive but have done the job) and I have found Vespids great for objectives etc. I love running solo XV9 Hazard Support's as well and they have performed.
Only one's that stick out
tbh
