I have mixed figures from the two makers. KC Normandy SS and CS Arnhem SS. The vehicles go together very well. The figures are another matter. If variances in figure size bother you, you will probably, IMO, have to pick one or the other maker. Size variances do not bother me so I like and mix them both. The CS figures are painted in a grittier, combat dirty style than KC. The CS figures are also a bit larger in stance and bulk. I have examples of figures from KC, CS, HB, and the odd NMA. CS is a tick larger, in MOST cases than KC, but CS really dwarfs HB and NMA (as well as early KC). Like I said though, I mix and match all makers as the size really doesn't bother me. Sorry I can't post pictures but I believe my description is accurate. -- lancer
