Is there any preference between straight cut ( |_| ) or 'U' shape

Makes no difference.
of corse it makes a difference! a joist with a smoothly shaped "U"
will be far stronger than a straight cut slot.

nope. Regs say no problems with a straight cut. Duh!

He never mentioned the regs. But structurally, a U shape will be
stronger. Read the famous 'Structures' book...

But it still will not make any difference in this case.
