I have Reaktor 4, i like it, but really, if you get it, it would be for the huge flexibility giving you the power to get just the sound you'd like. Especially in Reaktor 5 because you can go into the core cells(or whatever) and edit almost TOO much
. Well, the included esembles(instruments) can keep you entertained for the first month or so, but if you really want to use Reaktor it would be for extensive editing or creating all new synth and effect instances.
