I never bought into that feature because it limited your possibilities for change. When you buy a gun with that grip you're kinda stuck with it unless you spend more money to have it removed or put a sleeve over it. Both options make you spend money, not good for me.
The grip depends on what your going to be doing with it. most back yard shooters dont need anything special. But if your going to be shooting in 800 rounds in 45 degree rain than an aggressive grip is a god send. For me the RTF is still not aggressive enough, hence the stipple job.
