I can see where people would get this, but if it is true, it wouldn't matter too much. I use an ettin for slightly increase damage, but a zerk would hit from farther out. It's your choice, really. Damage (and maybe speed) or range?
macbeth explained this in my thread a little while ago:
"further range of zerker can be good (smite) and bad (charge). good for smite should be obvious, bad for charge because its harder to make a follow-up charge after hitting since you can only charge when your opponent is out of weapon range."
