I like Hacksaws, use them all the time, keep several with different blades at each workstation.
my favorite is the red handle, Klein, & 2 Miller Falls & a jewelers saw. (bottom 5) the rest are odds & ends; Sears, Stanley, Viking, nonames, etc..
I normally cut on the push stroke (Cuts faster), sometimes will use the pull for thin cuts (control), many times will install blade hooks opposite from each other, helps to prevent blade twisting on cheaper frames.
