The problem with dual row right angle is one row is shorter than the
other so cliping is needed (as you say).  Others may have better
skills than I...

I agree that if I have to make a lot of vias, might as well do TH. 
However, if its only a couple, vias are preferable. 

By the way,  I did a destructive test on the header I tried out.  Its
a stronger connection than TH.  I broke it off but pieces of FR4 came
with it!  Its all about surface area.
