I hope this might be helpful- here are some caparison photos of some of the figures in my collection.
Scale is a weird thing, as many different manufacturers have different ideas f what a 28mm figure should look like- as you can see these minis are all roughly the same size, but the difference in sculpting style, bulk and weapons size makes the world of difference- at the end of the day it's just down to preference.
