It's harder to control. Pushing the chisel cross grain makes for lots of 
chipping and splinters rather than shavings.

I'm not entirely sure, but string leveling seems to make the most obvious 
difference.

At least with the low angle laminate. Try a couple of notches in a scrap 
piece of Delignit. That stuff actively fights back.
