As far as a 5 inch trace (for example) be it arc, 
45 degree, or 90 degree  the inductance/inch 
and resistance/inch of a trace doesn't care. 
If you're asking for a significant difference, 
then it's a wash.

Expanding beyond this can get pretty hairy and alot 
of rocket science has gone into this topic. 

Suppose crosstalk needs to be minimized between 
traces. No matter what geometry is chosen, if the traces 
are physically very close to one another, then again, 
it won't matter.  They'll still crosstalk. 

There's been much discussion in the past on this topic 
and I'm sure someone out there can shed some more light.
