IME, the latter is bestest when dealing with cables that don't take twisting 
very well (semirigid cables and types with aluminum foil shields).  There will 
be minimal flexing.  The former imposes more twisting force on the cable.

PS: It took about 1-1/2 weeks to get a permit submittal appointment with 
Snohomish County for my tower.  The appointment is in 3 weeks.  FWIW, they're 
on a 20 hour workweek.
