Serato Vs Traktor

[sureno]

ok guys and girls, i want constructive answers here, valid points, experiences and knowledge. Modz1 did a similar thread but felt it got overlooked and wasn't quite as specific as this one. i ask this because im at a cross roads as to which one to buy. in my case i will be using a 2.6 MBP, i dont want to have to tweak or disable anything to run the system properly either. i fully understand that they both do similar jobs and can come down to preference but i believe their is more to it than simple preference, e.g why did technics 1210's become I.S all turntables play vinyl right? so im employing that kind of thinking behind it, also ssl and ts use different approaches (drivers) in there audio interfaces which i want opinions on too.

many thanks guys and girls if any
