If it becomes necessary to differentiate between separate forces & their leaders it would certainly be easier to see at a glance, they're ready in their storage box, but I haven't used 'em since SL days.
I prefer the late MMP counters in the regular German colours to be honest, but other games have used black with white print for Germans, so it's been a theme of sorts for a long time.
I always did like the bold red Russian berzerkers from SL, though.
I do also have some ss labelled dice, not to be fetishistic in any way, just to be more complete along with the other unit/formation/nationality sets of dice I have collected.
The precision dice in general do seem to be less streaky than most others.
The fancy dice and optional counters definitely add a little to the enjoyment for me.
